Pull input fixes from Dmitry Torokhov:
 "Fixes to various USB drivers to validate existence of endpoints before
  trying to use them, fixes to APLS v8 protocol, and a couple of i8042
  quirks"

  Input: ALPS - fix trackstick button handling on V8 devices
  Input: ALPS - fix V8+ protocol handling (73 03 28)
  Input: sur40 - validate number of endpoints before using them
  Input: kbtab - validate number of endpoints before using them
  Input: hanwang - validate number of endpoints before using them
  Input: yealink - validate number of endpoints before using them
  Input: ims-pcu - validate number of endpoints before using them

  Input: elan_i2c - add ASUS EeeBook X205TA special touchpad fw
  Input: i8042 - add TUXEDO BU1406 (N24_25BU) to the nomux list
  Input: synaptics-rmi4 - prevent null pointer dereference in f30
  Input: i8042 - add noloop quirk for Dell Embedded Box PC 3000

Input: sur40 - validate number of endpoints before using them

2017-03-16T20:56:54+00:00

Make sure to check the number of endpoints to avoid dereferencing a
NULL-pointer or accessing memory that lie beyond the end of the endpoint
array should a malicious device lack the expected endpoints.

lib/vsprintf.c: remove %Z support

2017-02-28T02:43:47+00:00

Now that %z is standartised in C99 there is no reason to support %Z.
Unlike %L it doesn't even make format strings smaller.

Use BUILD_BUG_ON in a couple ATM drivers.

In case anyone didn't notice lib/vsprintf.o is about half of SLUB which
is in my opinion is quite an achievement.  Hopefully this patch inspires
someone else to trim vsprintf.c more.

Prepare input updates for 4.11 merge window.

Input: zet6223 - export OF device ID as module aliases

2017-02-20T23:12:26+00:00

The I2C core always reports a MODALIAS of the form i2c: even if the
device was registered via OF, this means that exporting the OF device ID
table device aliases in the module is not needed. But in order to change
how the core reports modaliases to user-space, it's better to export it.

Before this patch:

$ modinfo drivers/input/touchscreen/zet6223.ko | grep alias
alias:          i2c:zet6223

After this patch:

$ modinfo drivers/input/touchscreen/zet6223.ko | grep alias
alias:          of:N*T*Czeitec,zet6223C*
alias:          of:N*T*Czeitec,zet6223
alias:          i2c:zet6223

Input: tsc2004/5 - switch to using generic device properties

2017-02-12T22:55:09+00:00

Instead of supporting legacy platform data (of which we have no mainline
users) and OF-based properties, let's switch to generic device properties.
This will still allow legacy boards to use the driver (by defining property
sets and attaching them to the drivers) and will simplify probe and make
driver usable on ACPI-based systems as well.

Input: tsc2004/5 - fix regulator handling

2017-02-12T22:55:08+00:00

In case of an optional regulator missing, regulator core will return
ERR_PTR(-ENOENT) and not NULL, so the check for missing regulator is
incorrect. Also, the regulator is not optional, it may simply be missing
from platform description, so let's use devm_regulator_get() and rely on
regulator core to give us dummy supply when real one is not available.

Input: tsc2005 - add OF device table

2017-02-12T22:55:08+00:00

To be prepared for SPI module loading using full compatible strings from
device tree, let's add OF module device table data.

Input: add driver for Zeitec ZET6223

2017-02-09T21:54:51+00:00

This is a basic driver for the Zeitec ZET6223 I2C touchscreen
controllers. The driver does not support firmware loading, which is not
required for all tablets which contain this chip.
