The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:
struct foo {
int stuff;
struct boo array[];
};
By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.
Also, notice that, dynamic memory allocations won't be affected by
this change:
"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]
This issue was found with the help of Coccinelle.

"The main change is that we are reverting blanket enablement of SMBus
mode for devices with Elan touchpads that report BIOS release date as
2018+ because there are older boxes with updated BIOSes that still do
not work well in SMbus mode.
We will have to establish whitelist for SMBus mode it looks like"

Revert "Input: elantech - enable SMBus on new (2018+) systems"
Input: synaptics-rmi4 - avoid processing unknown IRQs
Input: soc_button_array - partial revert of support for newer surface devices
Input: goodix - add support for 9-bytes reports
Input: da9063 - fix capability and drop KEY_SLEEP
Now that instances of input_dev support polling mode natively,
we no longer need to create input_polled_dev instance.

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

Recently we had a building error if we enable the MOUSE_PS2_ALPS while
disable the MOUSE_PS2_TRACKPOINT, and was fixed by 49e6979e7e
("Input: psmouse - fix build error of multiple definition").
We could improve that fix by dropping all unneeded functions and
CONFIG_MOUSE_ guards from the header, it is safe to do that since
those functions are not directly called by psmouse-base.c anymore.

We don't need dev_err() messages when platform_get_irq() fails now that
platform_get_irq() prints an error message itself when something goes
wrong. Let's remove these prints with a simple semantic patch.
// <smpl>
@@
expression ret;
struct platform_device *E;
@@
ret =
(
platform_get_irq(E, ...)
|
platform_get_irq_byname(E, ...)
);
if ( \( ret < 0 \| ret <= 0 \) )
{
(
-if (ret != -EPROBE_DEFER)
-{ ...
-dev_err(...);
-... }

...
-dev_err(...);
)
...
}
// </smpl>
While we're here, remove braces on if statements that only have one
