For Sitronix st1633 multi-touch controller driver the coordinates reported
for multiple fingers were wrong, as it was always taking LSB of coordinates
from the first contact data.

This reverts commit 883a2a80f79ca5c0c105605fafabd1f3df99b34c.

Apparently use dmi_get_bios_year() as manufacturing date isn't accurate
and this breaks older laptops with new BIOS update.

So let's revert this patch.

There are still new HP laptops still need to use SMBus to support all
features, but it'll be enabled via a whitelist.

rmi_process_interrupt_requests() calls handle_nested_irq() for
each interrupt status bit it finds. If the irq domain mapping for
this bit had not yet been set up, then it ends up calling
handle_nested_irq(0), which causes a NULL pointer dereference.

There's already code that masks the irq_status bits coming out of the
hardware with current_irq_mask, presumably to avoid this situation.
However current_irq_mask seems to more reflect the actual mask set
in the hardware rather than the IRQs software has set up and registered
for. For example, in rmi_driver_reset_handler(), the current_irq_mask
is initialized based on what is read from the hardware. If the reset
value of this mask enables IRQs that Linux has not set up yet, then
we end up in this situation.

There appears to be a third unused bitmask that used to serve this
purpose, fn_irq_bits. Use that bitmask instead of current_irq_mask
to avoid calling handle_nested_irq() on IRQs that have not yet been
set up.

<title>Input: soc_button_array - partial revert of support for newer surface devices</title>

<id>urn:sha1:bcf059578980526d6067a2b1b0cd8344b58bf2d5</id>
<content type='text'>
Commit c394159310d0 ("Input: soc_button_array - add support for newer
surface devices") not only added support for the MSHW0040 ACPI HID,
but for some reason it also makes changes to the error handling of the
soc_button_lookup_gpio() call in soc_button_device_create(). Note ideally
this seamingly unrelated change would have been made in a separate commit,
with a message explaining the what and why of this change.

I guess this change may have been added to deal with -EPROBE_DEFER errors,
but in case of the existing support for PNP0C40 devices, treating
-EPROBE_DEFER as any other error is deliberate, see the comment this
commit adds for why.

The actual returning of -EPROBE_DEFER to the caller of soc_button_probe()
introduced by the new error checking causes a serious regression:

On devices with so called virtual GPIOs soc_button_lookup_gpio() will
always return -EPROBE_DEFER for these fake GPIOs, when this happens
during the second call of soc_button_device_create() we already have
successfully registered our first child. This causes the kernel to think
we are making progress with probing things even though we unregister the
child before again before we return the -EPROBE_DEFER. Since we are making
progress the kernel will retry deferred-probes again immediately ending
up stuck in a loop with the following showing in dmesg:

[  124.022697] input: gpio-keys as /devices/platform/INTCFD9:00/gpio-keys.0.auto/input/input6537
[  124.040764] input: gpio-keys as /devices/platform/INTCFD9:00/gpio-keys.0.auto/input/input6538

[  124.202726] input: gpio-keys as /devices/platform/INTCFD9:00/gpio-keys.0.auto/input/input6547
&lt;continues on and on and on&gt;

And 1 CPU core being stuck at 100% and udev hanging since it is waiting
for the modprobe of soc_button_array to return.

This patch reverts the soc_button_lookup_gpio() error handling changes,
fixing this regression.

<title>Input: goodix - add support for 9-bytes reports</title>

<content type='text'>
Some variants of Goodix touchscreen firmwares use 9-bytes finger
report format instead of common 8-bytes format.

This report format may be present as:

struct goodix_contact_data {
        uint8_t unknown1;
        uint8_t track_id;
        uint8_t unknown2;
        uint16_t x;
        uint16_t y;
        uint16_t w;
}__attribute__((packed));

Add support for such format and use it for Lenovo Yoga Book notebook
(which uses a Goodix touchpad as a touch keyboard).

<content type='text'>
Since commit f889beaaab1c ("Input: da9063 - report KEY_POWER instead of
KEY_SLEEP during power key-press") KEY_SLEEP isn't supported anymore. This
caused input device to not generate any events if "dlg,disable-key-power"
is set.

Fix this by unconditionally setting KEY_POWER capability, and not
declaring KEY_SLEEP.

Pull input updates from Dmitry Torokhov:

 - input core allows hardware drivers to specify a [more precise]
   timestamp (normally taken in top half) to better track velocity of
   contacts

 - input_dev instances now support "polling" mode so that drivers could
   use the same object for polled and interrupt-driven operation. The
   plan is to convert existing drivers and retire input_polled_dev API

 - a new driver for the FlySky FS-iA6B RC receiver

 - a refresh of BU21013 touchpad driver

 - w90x900 keyboard and touchpad drivers are removed as the platform is
   gone

 - assorted fixes
