Pull input subsystem fixes from Dmitry Torokhov:
 "Simply small driver fixups"

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input:
  Input: ads7846 - remove redundant regulator_disable call
  Input: synaptics-rmi4 - fix register descriptor subpacket map construction
  Input: tegra-kbc - fix inverted reset logic
  Input: silead - use devm_gpiod_get
  Input: i8042 - set up shared ps2_cmd_mutex for AUX ports

ADS7846 regulator is disabled twice in a row in ads7846_remove(). Valid
one is in ads7846_disable().

Removing the ads7846 module causes warning about unbalanced disables.

The silead code is using devm_foo for everything (and does not free
any resources). Except that it is using gpiod_get instead of
devm_gpiod_get (but is not freeing the gpio_desc), change this
to use devm_gpiod_get so that the gpio will be properly released.

  Input: silead - remove some dead code
  Input: sis-i2c - select CONFIG_CRC_ITU_T
  Input: add driver for SiS 9200 family I2C touchscreen controllers
  Input: ili210x - fix permissions on "calibrate" attribute

  Input: add driver for Silead touchscreens
  Input: elantech - fix debug dump of the current packet
  Input: rotary_encoder - support binary encoding of states
  Input: xpad - power off wireless 360 controllers on suspend
  Input: i8042 - break load dependency between atkbd/psmouse and i8042
  Input: synaptics-rmi4 - do not check for NULL when calling of_node_put()
  Input: cros_ec_keyb - cleanup use of dev

buf[0] is an unsigned char.  touch_nr is an int.  The test for negative
here doesn't make sense so I have removed it.

The newly added sis_i2c driver fails to link without the CRC_ITU_T
driver enabled:

drivers/input/touchscreen/sis_i2c.o: In function `sis_ts_irq_handler':
sis_i2c.c:(.text+0xc0): undefined reference to `crc_itu_t'

This adds a Kconfig select statement.

"calibrate" attribute does not provide "show" methods and thus we should
not mark it as readable.

This driver adds support for Silead touchscreens. It has been tested
with GSL1680 and GSL3680 touch panels.

It supports ACPI and device tree enumeration. Screen resolution,
the maximum number of fingers supported and firmware name are
configurable.
