b829834016 asus-wmi: fix error handling in store_sys_wmi()
The asus_wmi_get_devstate_simple() returns 0-1 on success.  In theory
according to static checkers, it can return either -EIO or -ENODEV on
failure.  Currently the error handling code only handles -ENODEV and
-EIO is treated as success.  Let's make it handle the -EIO error as
well.

It's possible that it can't actually return -EIO and this patch is not
needed but in that case this patch is harmless and silences a static
checker warning so it's still worth it.

f71c882dd4 ideapad-laptop: Add Lenovo Yoga 900 to no_hw_rfkill dmi list
Like some of the other Yoga models the Lenovo Yoga 900 does not have a
hw rfkill switch, and trying to read the hw rfkill switch through the
ideapad module causes it to always reported blocking breaking wifi.

This commit adds the Lenovo Yoga 900 to the no_hw_rfkill dmi list, fixing
the wifi breakage.

c789fffc56 ideapad-laptop: include Yoga 3 1170 in add rfkill whitelist
This changes the entry to the whitelist of machines that do not have
a physical rfkill switch. Unfortunately, the Yoga 3 generation seems
to use upper-case letters for the YOGA 3 Pro-1370, while it uses normal
capitalization for its Yoga 3 1170 and 1470 siblings.

In order to catch all variants of the Yoga 3, I'm changing both
the entry for the 1470 (using "Yoga" as the name) and the entry for
the Pro 1370 (using all-caps "YOGA") to not match the exact model number
but only the generation. This way, the 1170 and 1470 models share one
entry, but if the firmware changes from one format to the other, it will
still work.

The second entry for Yoga 2 Pro that was recently added for some
reason ended up not being added in alphanumeric order, and I'm
moving the Yoga 3 1470 entry down while making the change, so they
are sorted more logically.

74caab996c ideapad-laptop: add support for Yoga 3 ESC key
The ideapad-laptop handles most special keys on various Lenovo Laptops
including the Yoga line. Unfortunately, the Yoga 3 11/13/14 models have
one important exception, which is the Fn-ESC combination.

On other Lenovo Laptops, this is FnLock, which switches the function keys
between the primary (Mute, Vol down, Vol up, ...) and the secondary (F1,
F2, F3, ...) behavior. On the new machines, FnLock is only available
through BIOS setup (possibly through a yet-to-be-implemented feature
in this driver) but not through Fn-ESC, but instead the ESC key itself
switched between ESC and a "Paper Display" app for Windows.

Unfortunately, that means that you can never have both ESC *and* the
function keys working at the same time without needing to press Fn on
one of them.
As pointed out in the official Lenovo Forum by dozens of users, this
makes the machine rather useless for any serious work [1].

I have now studied the ACPI DSDT one more time and found the event
that is generated for the ESC key. Unlike all other key events on this
machine, it is actually a WMI, while the other ones are read from the
embedded controller.

I am now installing a WMI notifier that uses the event number from the
WMI subsystem as the scancode. The only event number generated here is
'128', and that fits in nicely with the two existing ranges of scancodes
used by the EC: 0-15 for the 16-bit VPCCMD_R_VPC register, 16-17 for
the VPCCMD_R_NOVO register and 64-67 for VPCCMD_R_SPECIAL_BUTTONS.

The only sane way to handle this button (in absence of the Windows Paper
Display driver) seems to be to have it emit KEY_ESC, so that is what
I use as the default. Should any user ever want to overwrite the default,
they can install their own keymap.

To ensure that we can still build the driver without adding a CONFIG_WMI
dependency, all new code is enclosed in #ifdef.

The thinkpad_acpi driver currently emits error messages on unsupported
brightness interfaces, giving the impression that someone will implement
those. However, this error is spit out on nearly every thinkpad in
production since 2 years now. Furthermore, the backlight interfaces on
those devices are supported by the i915 driver just fine.

Downgrade the error message to a normal pr_info() and stop telling people
to report it to IBM.

This patch initializes such variable to avoid such unwanted effects.

c460228086 acer-wmi: remove threeg and interface sysfs interfaces
Since v3.0 kernel, acer-wmi driver auto detects internal 3G device and
provides the threeg rfkill interface. So the sysfs interface of 3G is
no longer necessary now.

The 7b8aca65 patch added kernel information log to remind to user space
for the threeg sysfs interface will be removed in 2012, then b58b9ffc patch
updated the interface removing time to 2014.

I think the 3 years lead time is enough for user space application to use
rfkill instead of sysfs interface to control 3G device.

This patch removes code about threeg sysfs interface. And it also removes the
unused interface sysfs that exposes which ACPI-WMI method used by acer-wmi
driver on the machine. The information is already exposed by the acer-wmi
initial log.

14991fc7df platform/x86: Toshiba WMI Hotkey Driver
Toshiba laptops that feature WMI events for hotkeys were left unsupported
by the toshiba_acpi driver, however, commit a88bc06e5a ("toshiba_acpi:
Avoid registering input device on WMI event laptops") added hardware
support for such laptops, but the hotkeys are not handled there.

This driver adds support for hotkey monitoring on certain Toshiba laptops
that manage the hotkeys via WMI events instead of the Toshiba
Configuration Interface (TCI).

The toshiba_acpi driver and this one can co-exist, as this only takes
care of hotkeys, while the proper takes care of hardware related stuff.

Currently the driver is under the EXPERIMENTAL flag, as the keymap
and the notify function are incomplete (due to lack of hardware to test).

53147b6cab toshiba_acpi: Fix hotkeys registration on some toshiba models
Commit a2b3471b5b ("toshiba_acpi: Use the Hotkey Event Type function
for keymap choosing") changed the *setup_keyboard function to query for
the Hotkey Event Type to help choose the correct keymap, but turns out
that here are certain Toshiba models out there not implementing this
feature, and thus, failing to continue the input device registration and
leaving such laptops without hotkey support.

This patch changes such check, and instead of returning an error if
the Hotkey Event Type is not present, we simply inform userspace about it,
changing the message printed from err to notice, making the function
responsible for registering the input device to continue.

This issue was found on a Toshiba Portege Z30-B, but there might be
some other models out there affected by this regression as well.

85b4e4eb2f wmi: Remove private %pUL implementation
The work performed by wmi_gtoa is equivalent to simply sprintf(out,
"%pUL", in), so one could replace its body by this. However, most
users feed the result directly as a %s argument to some other function
which also understands the %p extensions (they all ultimately use
vsnprintf), so we can eliminate some stack buffers and quite a bit of
code by just using %pUL directly.

In wmi_dev_uevent I'm not sure whether there's room for a
nul-terminator in env->buf, so I've just replaced wmi_gtoa with the
equivalent sprintf call.

efd85cf86a thinkpad_acpi: Remove side effects from vdbg_printk -> no_printk macro
vdbg_printk when not using CONFIG_THINKPAD_ACPI_DEBUG uses
no_printk which produces no logging output but always
evaluates arguments.

Change the macro to surround the no_printk call with
	do { if (0) no_printk(...); } while (0)
to avoid the unnecessary argument evaluations.

2508a45a92 surface pro 3: Add support driver for Surface Pro 3 buttons
Since Surface Pro 3 does not follow the specs of "Windows ACPI Design
Guide for SoC Platform", code in drivers/input/misc/soc_array.c can
not detect these buttons on it. According to bios implementation,
Surface Pro 3 encapsulates these buttons in a device named "VGBI",
with _HID "MSHW0028". When any of the buttons is pressed, a specify
ACPI notification code for this button will be delivered to "VGBI". For
example, if power button is pressed down, ACPI notification code of 0xc6
will be sent by Notify(VGBI, 0xc6).

This patch leverages "VGBI" to distinguish different ACPI notification
code from Power button, Home button, Volume button, then dispatches these
code to input layer. Lid is already covered by acpi button driver, so
there's no need to rewrite.

420b54de25 mfd: watchdog: iTCO_wdt: Expose watchdog properties using platform data
Intel Sunrisepoint (Skylake PCH) has the iTCO watchdog accessible across
the SMBus, unlike previous generations of PCH/ICH where it was on the
LPC bus. Because it's on the SMBus, it doesn't make sense to pass around
a 'struct lpc_ich_info', and leaking the type of bus into the iTCO
watchdog driver is kind of backwards anyway.

This change introduces a new 'struct itco_wdt_platform_data' for use
inside the iTCO watchdog driver and by the upcoming Intel Sunrisepoint
code, which neatly avoids having to include lpc_ich headers in the i801
i2c driver.

This change is overdue because lpc_ich_info has already found its way
into other TCO watchdog users, notably the intel_pmc_ipc driver where
the watchdog actually isn't on the LPC bus as far as I can see.

A simple translation layer is provided for converting from the existing
'struct lpc_ich_info' inside the lpc_ich mfd driver.

6d212b8adc ideapad-laptop: add alternative representation for Yoga 2 to DMI table
There is at least one (mine) Yoga 2 Pro in existence that has incorrect
product version stored in DMI (reading as "INVALID"), causing it to not be
recognized as Yoga 2 by ideapad-laptop module, which in turn causes
non-existent hardware rfkills to be always reported as blocked.

This change adds a second check by board name, which is "Yoga2".
Looks like it also happens to be "INVALID" on some other Yoga 2 machines
where product version is correct instead, so the original check is left
intact to catch both cases.

97ade7697b asus-laptop: Add key found on Asus F3M
Asus F3M has two keys labeled with an icon of a touchpad. The first,
reported as 0x6B is next to the power key and the second, reported as
0x6A, is F9 combined with Fn button. When I was pressing the latter, I was
getting "Unknown key 6a pressed" message before applying this patch.

Asus F3M does not support WMI so the commit does not update key mappings
in the asus-nb-wmi.c file.

I have not tested this mapping on any other Asus laptop.

a6b5354f42 toshiba_acpi: Remove unnecessary checks and returns in HCI/SCI functions
A previous patch added explicit feature checks for support, *SUCCESS*
and *FAILURE to the HCI/SCI *{get, set} functions.

This patch removes some unnedded checks to the driver HCI/SCI
functions given that the default error return value is now set to
-EIO, there is no need to check for other error values other than
the ones currently checking for.

e1a949c1b9 toshiba_acpi: Refactor *{get, set} functions return value
This patch refactors the return value of the driver *{get, set}
functions, since the driver default error value is -EIO.

All the functions now check for TOS_FAILURE, TOS_NOT_SUPPORTED and
TOS_SUCCESS.

On TOS_FAILURE a pr_err message is printed informing the user of the
error (no change was made to this, except the check was added to the
functions not checking for this).

On TOS_NOT_SUPPORTED we now return -ENODEV immediately (some
functions were returning -EIO and some other were not checking)

On TOS_SUCCESS* we now return 0 (as a side effect, a new success value
was added, since some functions return one instead of zero to
indicate success).

As a special case, the LED functions now check for *FAILURE on
*set, and check for TOS_FAILURE and TOS_SUCCESS on *get with their
"default" return value set to LED_OFF.

Also the {lcd, video}_proc* functions were adapted to reflect these
changes to their parent HCI functions.
