Andi Shyti c4beedb8a9 Input: tm2-touchkey - use LEN_ON as boolean value instead of LED_FULL 
Commit 4e552c8cb5 ("leds: add LED_ON brightness as boolean value")
has introduced the LED_ON enumeration value that can be used
instead of LED_FULL which has more of a linear value.

Because the tm2-touchscreen doesn't have brightness levels, but
it's a simple on/off led, use LED_ON instead of LED_FULL.

Guenter Roeck 14fdb924af Input: keyboard - drop unnecessary calls to input_set_drvdata 
If there is no call to dev_get_drvdata() or input_get_drvdata(),
the call to input_set_drvdata() is unnecessary and can be dropped.

Jaechul Lee 72d1f2346d Input: tm2-touchkey - add touchkey driver support for TM2 
This patch adds support for the TM2 touch key and led functionality.

The driver interfaces with userspace through an input device and reports
KEY_PHONE and KEY_BACK event types. LED brightness can be controlled by
"/sys/class/leds/tm2-touchkey/brightness".
