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 map_offset variable is specific to the register and needs to be reset
in the loop. Otherwise, subsequent register's subpacket maps will have
their bits set at the wrong index.

Commit fe6b0dfaba68 ("Input: tegra-kbc - use reset framework")
accidentally converted _deassert to _assert, so there is no code
to wake up this hardware.

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.

The commit 4097461897df ("Input: i8042 - break load dependency ...")
correctly set up ps2_cmd_mutex pointer for the KBD port but forgot to do
the same for AUX port(s), which results in communication on KBD and AUX
ports to clash with each other.

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.
