The function rmi_2d_sensor_set_input_params is declared static and marked
EXPORT_SYMBOL_GPL, which is at best an odd combination. Because the
function is not used outside of the drivers/input/rmi4/rmi_2d_sensor.c
file it is defined in, this commit removes the EXPORT_SYMBOL_GPL() marking.

There are some new HP laptops with Elantech touchpad that don't support
multitouch.
Currently we use ETP_NEW_IC_SMBUS_HOST_NOTIFY() to check if SMBus is supported,
but in addition to firmware version, the bus type also informs us whether the IC
can support SMBus. To avoid breaking old ICs, we will only enable SMbus support
based the bus type on systems manufactured after 2018.
Lastly, let's consolidate all checks into elantech_use_host_notify() and use it
to determine whether to use PS/2 or SMBus.

The keyboard and trackpad on recent MacBook's (since 8,1) and
MacBookPro's (13,* and 14,*) are attached to an SPI controller instead
of USB, as previously. The higher level protocol is not publicly
documented and hence has been reverse engineered. As a consequence there
are still a number of unknown fields and commands. However, the known
parts have been working well and received extensive testing and use.
In order for this driver to work, the proper SPI drivers need to be
loaded too; for MB8,1 these are spi_pxa2xx_platform and spi_pxa2xx_pci;
for all others they are spi_pxa2xx_platform and intel_lpss_pci.

On a latest Lenovo laptop, the trackpoint and 3 buttons below it
don't work at all, when we move the trackpoint or press those 3
buttons, the kernel will print out:
"Rejected trackstick packet from non DualPoint device"
This device is identified as an alps touchpad but the packet has
trackpoint format, so the alps.c drops the packet and prints out
the message above.
According to XiaoXiao's explanation, this device is named cs19 and
is trackpoint-only device, its firmware is only for trackpoint, it
is independent of touchpad and is a device completely different from
DualPoint ones.
To drive this device with mininal changes to the existing driver, we
just let the alps driver not handle this device, then the trackpoint.c
will be the driver of this device if the trackpoint driver is enabled.
(if not, this device will fallback to a bare PS/2 device)
With the trackpoint.c, this trackpoint and 3 buttons all work well,
they have all features that the trackpoint should have, like
scrolling-screen, drag-and-drop and frame-selection.

- the second one teaches stream_open.cocci to consider files as being
stream-like even if they use noop_llseek. It results in two more
drivers being converted to stream_open() (mousedev.c and
hid-sensor-custom.c)"
* tag 'stream_open-5.3' of https://lab.nexedi.com/kirr/linux:
*: convert stream-like files -> stream_open, even if they use noop_llseek
This patch continues 10dce8af34 (fs: stream_open - opener for
stream-like files so that read and write can run simultaneously without
deadlock) and c5bf68fe0c (*: convert stream-like files from
nonseekable_open -> stream_open) and teaches steam_open.cocci to
consider files as being stream-like not only if they have
.llseek=no_llseek, but also if they have .llseek=noop_llseek.
This is safe to do: the comment about noop_llseek says
This is an implementation of ->llseek useable for the rare special case when
userspace expects the seek to succeed but the (device) file is actually not
able to perform the seek. In this case you use noop_llseek() instead of
falling back to the default implementation of ->llseek.
and in general noop_llseek was massively added to drivers in 6038f373a3
(llseek: automatically add .llseek fop) when changing default for NULL .llseek
from NOP to no_llseek with the idea to avoid breaking compatibility, if
maybe some user-space program was using lseek on a device without caring
about the result, but caring if it was an error or not.
Amended semantic patch produces two changes when applied tree-wide:
drivers/hid/hid-sensor-custom.c:690:8-24: WARNING: hid_sensor_custom_fops: .read() has stream semantic; safe to change nonseekable_open -> stream_open.
drivers/input/mousedev.c:564:1-17: ERROR: mousedev_fops: .read() can deadlock .write(); change nonseekable_open -> stream_open to fix.

The GTCO tablet input driver configures itself from an HID report sent
via USB during the initial enumeration process. Some debugging messages
are generated during the parsing. A debugging message indentation
counter is not bounds checked, leading to the ability for a specially
crafted HID report to cause '-' and null bytes be written past the end
of the indentation array. As long as the kernel has CONFIG_DYNAMIC_DEBUG
enabled, this code will not be optimized out. This was discovered
during code review after a previous syzkaller bug was found in this

Pull power management updates from Rafael Wysocki:
"These update PCI and ACPI power management (improved handling of ACPI
power resources and PCIe link delays, fixes related to corner cases,
hibernation handling rework), fix and extend the operating performance
points (OPP) framework, add new cpufreq drivers for Raspberry Pi and
imx8m chips, update some other cpufreq drivers, clean up assorted
pieces of PM code and documentation and update tools.
Specifics:
- Improve the handling of shared ACPI power resources in the PCI bus
type layer (Mika Westerberg).
- Make the PCI layer take link delays required by the PCIe spec into
account as appropriate and avoid polling devices in D3cold for PME
(Mika Westerberg).
- Fix some corner case issues in ACPI device power management and in
the PCI bus type layer, optimiza and clean up the handling of
runtime-suspended PCI devices during system-wide transitions to
sleep states (Rafael Wysocki).
- Rework hibernation handling in the ACPI core and the PCI bus type
to resume runtime-suspended devices before hibernation (which
allows some functional problems to be avoided) and fix some ACPI
power management issues related to hiberation (Rafael Wysocki).
- Extend the operating performance points (OPP) framework to support
a wider range of devices (Rajendra Nayak, Stehpen Boyd).
- Fix issues related to genpd_virt_devs and issues with platforms
using the set_opp() callback in the OPP framework (Viresh Kumar,
Dmitry Osipenko).
- Add new cpufreq driver for Raspberry Pi (Nicolas Saenz Julienne).
- Add new cpufreq driver for imx8m and imx7d chips (Leonard Crestez).
- Fix and clean up the pcc-cpufreq, brcmstb-avs-cpufreq, s5pv210, and
armada-37xx cpufreq drivers (David Arcari, Florian Fainelli, Paweł
Chmiel, YueHaibing).
- Clean up and fix the cpufreq core (Viresh Kumar, Daniel Lezcano).
- Fix minor issue in the ACPI system sleep support code and export
one function from it (Lenny Szubowicz, Dexuan Cui).
- Clean up assorted pieces of PM code and documentation (Kefeng Wang,
Andy Shevchenko, Bart Van Assche, Greg Kroah-Hartman, Fuqian Huang,
Geert Uytterhoeven, Mathieu Malaterre, Rafael Wysocki).
- Update the pm-graph utility to v5.4 (Todd Brandt).

One of the more common cases of allocation size calculations is finding
the size of a structure that has a zero-sized array at the end, along
with memory for some number of elements for that array. For example:
struct gpio_keys_drvdata {
...
struct gpio_button_data data[0];
};
size = sizeof(struct gpio_keys_drvdata) + count * sizeof(struct gpio_button_data);
instance = devm_kzalloc(dev, size, GFP_KERNEL);
Instead of leaving these open-coded and prone to type mistakes, we can
now use the new struct_size() helper:
instance = devm_kzalloc(dev, struct_size(instance, data, count), GFP_KERNEL);
Notice that, in this case, variable size is not necessary, hence it
is removed.
This code was detected with the help of Coccinelle.

The name of pm_suspend_via_s2idle() is confusing, as it doesn't
reflect the purpose of the function precisely enough and it is
very similar to pm_suspend_via_firmware(), which has a different
purpose, so rename it as pm_suspend_default_s2idle() and update
its only caller, i8042_register_ports(), accordingly.

They are capable of using intertouch and it works well with
psmouse.synaptics_intertouch=1, so add them to the list.
Without it, scrolling and gestures are jumpy, three-finger pinch gesture
doesn't work and three- or four-finger swipes sometimes get stuck.

Instead of filling in the struct v4l2_capability device_caps
field, fill in the struct video_device device_caps field.
That way the V4L2 core knows what the capabilities of the
video device are.
But this only really works if all drivers use this, so convert
this touchscreen driver accordingly.

There are several scenarios that keyboard can NOT wake up system
from suspend, e.g., if a keyboard is depressed between system
device suspend phase and device noirq suspend phase, the keyboard
ISR will be called and both keyboard depress and release interrupts
will be disabled, then keyboard will no longer be able to wake up
system. Another scenario would be, if a keyboard is kept depressed,
and then system goes into suspend, the expected behavior would be
when keyboard is released, system will be waked up, but current
implementation can NOT achieve that, because both depress and release
interrupts are disabled in ISR, and the event check is still in
progress.
To fix these issues, need to make sure keyboard's depress or release
interrupt is enabled after noirq device suspend phase, this patch
moves the suspend/resume callback to noirq suspend/resume phase, and
enable the corresponding interrupt according to current keyboard status.

Calling input_mt_init_slots() copies ABS_MT_POSITION_X to ABS_X and
so on, but doing so before calling touchscreen_parse_properties()
leaves ABS_X min = max = 0 which may prompt an X server to ignore
the device.
To solve this problem, wait to call input_mt_init_slots() until all
absolute axis information has been resolved (whether that's through
device tree via touchscreen_parse_properties() or from reading from
the device directly).
