Pull input fixes from Dmitry Torokhov:

 - a tweak to uinput interface to reject requests with abnormally large
   number of slots. 100 slots/contacts should be enough for real devices

 - support for FocalTech FT8201 added to the edt-ft5x06 driver

 - tweaks to i8042 to handle more devices that have issue with its
   emulation

 - Synaptics touchpad switched to native SMbus/RMI mode on HP Elitebook
   840 G2

 - other minor fixes

We need to read a u32 value (4 bytes), not size of a pointer to that
value.

Also, himax_read_mcu() wrapper is an overkill, remove it and use
himax_bus_read() directly.

The driver supports the FT8201 chip as well. It registers up to 10 touch
points.

We only had a couple of array[] declarations, and changing them to just
use 'MAX()' instead of 'max()' fixes the issue.

This will allow us to simplify our min/max macros enormously, since they
can now unconditionally use temporary variables to avoid using the
argument values multiple times.

In case the touch controller is not connected, this message keeps scrolling
on the console indefinitelly. Ratelimit it to avoid filling kernel logs.

Pull input updates from Dmitry Torokhov:

 - streamlined logic in input core for handling normal input handlers vs
   input filters

 - updates to input drivers to allocate memory with sizeof(*pointer)
   instead of sizeof(type)

 - change to ads7846 touchscreen driver to use hsync GPIO instead of
   requiring platform data with special method (which is not compatible
   with boards using device tree)

 - update to adc-joystick driver to handle inverted axes

 - cleanups in various drivers switching them to use the new "guard" and
   "__free()" facilities

 - changes to several drivers (adxl34x, atmel_mxt_ts, ati-remote2,
   omap-keypad, yealink) to stop creating driver-specific device
   attributes manually and use driver core facilities for this

 - update to Cypress PS/2 protocol driver to properly handle errors from
   the PS/2 transport as well as other cleanups

 - update to edt-ft5x06 driver to support ft5426 variant

 - update to ektf2127 driver to support ektf2232 variant

 - update to exc3000 driver to support EXC81W32 variant

 - update to imagis driver to support IST3038 variant

 - other assorted driver cleanups.

The HX83100A is a bit of an outlier in the Himax HX831xxx series of
touch controllers as it requires reading touch events through the AHB
interface of the MCU rather than providing a dedicated FIFO address like
the other chips do.
This patch implements the specific read function and introduces the
HX83100A chip with an appropriate i2c ID and DT compatible string.

The HX83100A doesn't have a straightforward way to do chip
identification, which is why it is not implemented in this patch.
