According to Documentation/CodingStyle - Chapter 14:

"The preferred form for passing a size of a struct is the following:

        p = kmalloc(sizeof(*p), ...);

The alternative form where struct name is spelled out hurts readability and
introduces an opportunity for a bug when the pointer variable type is changed
but the corresponding sizeof that is passed to a memory allocator is not."

So do it as recommended.

e9e8520f22 Input: synaptics - use in-kernel tracking for reporting mt data
The current code tries to consider all states and transitions to properly
detect which finger is attached to which slot. The code is quite huge
and difficult to read.

If the sensor manages to group the touch points but is not reliable in
giving tracking ids, we can simply use the kernel tracking method. Note
that it is already used by Cr-48 Chromebooks.

Incidentaly, this fixes a bug reported by Peter Hutterer:
"""
on the Lenovo T440, run:
evemu-record /dev/input/event4 | grep BTN_

then put one, two, three, two fingers down
when you go from 3 to 2 fingers the driver sends a spurious BTN_TOUCH 0
event:

E: 0.000000 0001 014a 0001      # EV_KEY / BTN_TOUCH            1
E: 0.000000 0001 0145 0001      # EV_KEY / BTN_TOOL_FINGER      1
E: 0.770008 0001 0145 0000      # EV_KEY / BTN_TOOL_FINGER      0

E: 1.924716 0001 014d 0000      # EV_KEY / BTN_TOOL_DOUBLETAP   0
E: 1.924716 0001 014e 0001      # EV_KEY / BTN_TOOL_TRIPLETAP   1

.. changing from 3 to 2 fingers now

E: 3.152641 0001 014a 0000      # EV_KEY / BTN_TOUCH            0
E: 3.152641 0001 014d 0001      # EV_KEY / BTN_TOOL_DOUBLETAP   1

E: 3.176948 0001 014a 0001      # EV_KEY / BTN_TOUCH            1

quick look in the kernel shows it's caused by hw.z going to 0 for a packet,
so probably a firmware bug. either way, it makes it hard to track BTN_TOUCH
as signal that at least one finger is down.
"""

The in-kernel tracking is enough to remove this spurious BTN_TOUCH 0.

d27eb7931c Input: alps - v7: fix finger counting for > 2 fingers on clickpads
Protocol v7 uses the middle / right button bits on clickpads to communicate
"location" information of a 3th touch (and possible 4th) touch on
clickpads.

Specifically when 3 touches are down, if one of the 3 touches is in the
left / right button area, this will get reported in the middle / right
button bits and the touchpad will still send a TWO type packet rather then
a MULTI type packet, so when this happens we must add the finger reported
in the button area to the finger count.

Likewise we must also add fingers reported this way to the finger count
when we get MULTI packets.

7091c443dd Input: alps - v7: sometimes a single touch is reported in mt[1]
The v7 proto differentiates between a primary touch (with high precision)
and a secondary touch (with lower precision). Normally when 2 fingers are
down and one is lifted the still present touch becomes the primary touch,
but some traces have shown that this does not happen always.

This commit deals with this by making alps_get_mt_count() not stop at the
first empty mt slot, and if a touch is present in mt[1] and not mt[0]
moving the data to mt[0] (for input_mt_assign_slots).

8b23811535 Input: alps - v7: ignore new packets
NEW packets are send to indicate a discontinuity in the finger coordinate
reporting. Specifically a finger may have moved from slot 0 to 1 or vice
versa.  INPUT_MT_TRACK takes care of this for us.

NEW packets have 3 problems:
1) They do not contain middle / right button info (on non clickpads)
   this can be worked around by preserving the old button state
2) They do not contain an accurate fingercount, and they are
   typically send when the number of fingers changes. We cannot use
   the old finger count as that may mismatch with the amount of
   touch coordinates we've available in the NEW packet
3) Their x data for the second touch is inaccurate leading to
   a possible jump of the x coordinate by 16 units when the first
   non NEW packet comes in

Since problems 2 & 3 cannot be worked around, just ignore them.

aac8bcf1ed Input: evdev - add CLOCK_BOOTTIME support
This patch adds support for CLOCK_BOOTTIME for input event timestamp.
CLOCK_BOOTTIME includes suspend time, so it would allow aplications
to get correct time difference between two events even when system
resumes from suspend state.

2ba3532047 Input: psmouse - expose drift duration for IBM trackpoints
IBM Trackpoints have a feature to compensate for drift by recalibrating
themselves periodically. By default, if for 0.5 seconds there is no change
in position, it's used as the new zero. This duration is too low. Often,
the calibration happens when the trackpoint is in fact being used.

IBM's Trackpoint Engineering Specifications show a configuration register
that allows changing this duration, rstdft1.

Expose it via sysfs among the other settings.

Pull input subsystem updates from Dmitry Torokhov:
 "Two new drivers for Elan hardware (for I2C touchpad and touchscreen
  found in several Chromebooks and other devices), a driver for Goodix
  touch panel, and small fixes to Cypress I2C trackpad and other input
  drivers.

  Also we switched to use __maybe_unused instead of gating suspend/
  resume code with #ifdef guards to get better compile coverage"

7c12a5b19e Input: stmpe - bias keypad columns properly
All keypad column pins used as inputs should be pulled up on the STMPE24xx,
but this is not done by the current driver.  Add some logic that will do
this properly. The STMPE1601 also has a keypad controller, but explicitly
does *NOT* require you to set up any pull-ups.

8ed9255676 Input: gpio_keys - replace timer and workqueue with delayed workqueue
We do not need to roll our own implementation of delayed work now that we
have proper implementation of mod_delayed_work.

For interrupt-only driven buttons we retain the timer, but we rename
it to release_timer to better reflect its purpose.

This change allows specify interrupt for buttons separately form gpio,
potentially allowing to form several "clusters" of buttons on
different interrupts.

Button defined without both gpio and irq in device tree is a hared error
instead of a warning now.
