b6ad9a26e7 HID: usbhid: Fix for the WiiU adapter from Mayflash
The WiiU adapter from Mayflash (see
http://www.mayflash.com/Products/NINTENDOWiiU/W009.html) is not
working correctly.

The "XInput" mode works fine, the controller is recognized as a xbox
controller. But it is only possible to connect one controller with this method.

In "DInput" mode the device is recognized as some kind of mouse input but no
joystick is created. This commit will change this behavior with
HID_QUIRK_MULTI_INPUT to split the device into 4 input devices so that it will
also create joysticks in /dev/input/js*.

Looks like 0x8882 needs the same quirk than 0x8883.
Given that both devices claim they are "TPV OpticalTouchScreen" rename
the 0x8883 to add its PID in the #define.

3af4e5a951 HID: usbhid: Fix the check for HID_RESET_PENDING in hid_io_error
It was reported that after 10-20 reboots, a usb keyboard plugged
into a docking station would not work unless it was replugged in.

Using usbmon, it turns out the interrupt URBs were streaming with
callback errors of -71 for some reason.  The hid-core.c::hid_io_error was
supposed to retry and then reset, but the reset wasn't really happening.

The check for HID_NO_BANDWIDTH was inverted.  Fix was simple.

Tested by reporter and locally by me by unplugging a keyboard halfway until I
could recreate a stream of errors but no disconnect.

d6ea2f88ac HID: usbhid: Add a quirk for raphnet multi-gamepad adapters
The raphnet.net 4nes4snes and 2nes2snes multi-joystick adapters use a single
HID report descriptor with one report ID per controller. This has the effect
that the inputs of otherwise independent game controllers get packed in one
large joystick device.

With this patch each controller gets its own /dev/input/jsX device, which is
more natural and less confusing than having all inputs going to the same place.

e8f46e4f93 HID: pidff: support more than one concurrent effect
The PID driver (usbhid/hid-pidff.c) does not set the effect ID when
uploading an effect. The result is that the initial upload works but
subsequent uploads to modify effect parameters are all directed at the
last-created effect.

The targeted effect ID must be passed back to the device when effect
parameters are changed. This is done at the start of
"pidff_set_condition_report", "pidff_set_periodic_report" etc. based on
the value of "pidff->block_load[PID_EFFECT_
BLOCK_INDEX].value[0]".

This value is only ever set during pidff_request_effect_upload.
The result is stored in "pidff->pid_id[effect->id]" at the end of
pid_upload_effect, for later use. However, if an effect is modified and
re-sent then this identifier is not being copied back from
pidff->pid_id[effect->id] before sending the command to the device. The
fix is to do this at the start of pidff_upload_effect.

70b69cfb88 HID: uclogic: Set quirks from inside the driver
Based on a patch from: Nikolai Kondrashov <Nikolai.Kondrashov@redhat.com>

Most of the tablets handled by hid-uclogic already use MULTI_INPUT.
For the ones which are not quirked in usbhid/hidquirks, they have a
custom report descriptor which contains only one report per HID
interface. For those tablets HID_QUIRK_MULTI_INPUT is transparent.

According to https://github.com/DIGImend/tablets, the only problematic
tablet currently handled by hid-uclogic is the TWHA60 v3. This tablet
presents different report descriptors from the ones currently quirked.
This is not a problem per se, given that this tablet is not supported
currently in this version (it needs the same command as a Huion to
start forwarding events).

afd700d933 HID: pidff: Fix initialisation forMicrosoft Sidewinder FF Pro 2
The FF2 driver (usbhid/hid-pidff.c) sends commands to the stick during ff_init.
However, this is called inside a block where driver_input_lock is locked, so
the results of these initial commands are discarded. This behavior is the
"killer", without this nothing else works.

ff_init issues commands using "hid_hw_request". This eventually goes to
hid_input_report, which returns -EBUSY because driver_input_lock is locked. The
change is to delay the ff_init call in hid-core.c until after this lock has
been released.

Calling hid_device_io_start() releases the lock so the device can be
configured.  We also need to call hid_device_io_stop() on exit for the lock to
remain locked while ending the init of the drivers.

b905811a49 HID: usbhid: prevent unwanted events to be sent when re-opening the device
When events occurs while no one is listening to the node (hid->open == 0
and usb_kill_urb() called) some events are still stacked somewhere in
the USB (kernel or device?) stack. When the node gets reopened, these
events are drained, and this results in spurious touch down/up, or mouse
button clicks.

The problem was spotted with touchscreens in fdo bug #81781 [1], but it
actually occurs with any mouse using hid-generic or touchscreen.

A way to reproduce it is to call:

$ xinput disable 9 ; sleep 5 ; xinput enable 9

With 9 being the device ID for the touchscreen/mouse. During the "sleep",
produce some touch events or click events. When "xinput enable" is called,
at least one click is generated.

This patch tries to fix this by draining the queue for 50 msec and
during this time frame, not forwarding these old events to the hid layer.

Hans completed the explanation:
"""
Devices like mice (basically any hid device) will have a fifo
on the device side, when we stop submitting urbs to get hid reports from
it, that fifo will fill up, and when we resume we will get whatever
is there in that fifo.

Without this quirk the device keeps disconnecting from the bus (and is

occur).

Note that while the device can be run-time suspended, the autosuspend
timeout must be high enough to allow the device to be polled at least
once before being suspended. Specifically, using autosuspend_delay_ms=0
will still cause the device to disconnect on input events.

This is needed for devices that disconnects from the bus unless the
interrupt endpoint has been polled at least once or when not responding
to an input event (e.g. after having shut down X).

8f507ef522 HID: usbhid: improve handling of Clear-Halt and reset
This patch changes the way usbhid carries out Clear-Halt and reset.

Currently, after a Clear-Halt on the interrupt-IN endpoint, the driver
immediately restarts the interrupt URB, even if the Clear-Halt failed.
This doesn't work out well when the reason for the failure was that
the device was disconnected (when a low- or full-speed device is
connected through a hub to an EHCI controller, transfer errors caused
by disconnection are reported as stalls by the hub).  Instead now the
driver will attempt a reset after a failed Clear-Halt.

The way resets are carried out is also changed.  Now the driver will
call usb_queue_reset_device() instead of calling usb_reset_device()
directly.  This avoids a deadlock that would arise when a device is
unplugged: The hid_reset() routine runs as a workqueue item, a reset
attempt after the device has been unplugged will fail, failure will
cause usbhid to be unbound, and the disconnect routine will try to do
cancel_work_sync().  The usb_queue_reset_device() implementation is
carefully written to handle scenarios like this one properly.

46df9dedab HID: usbhid: Use flag HID_DISCONNECTED when a usb device is removed
Set disconnected flag in struct usbhid when a usb device is removed. Check for
disconnected flag before sending urb requests. This prevents a kernel panic
when a hid driver calls hid_hw_request() after removing a usb device.
