Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input
Pull input subsystem updates from Dmitry Torokhov: "You will get - a new driver for Elan eKTF2127 touchscreen controllers - a new "gpio-decoder" driver to read and report state of several GPIO lines - an ADC resistor ladder driver - the ft6326 driver is removed because edt-ft5x06 handles the same devices just fine. .. plus the regular slew of driver fixes/enhancements" * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input: (26 commits) Input: elan_i2c - fix return tests of i2c_smbus_read_block_data() Input: ektf2127 - mark PM functions as __maybe_unused Input: snvs_pwrkey - drop input_free_device call if input_register_device fails Input: add support for Elan eKTF2127 touchscreen controller Input: serio - add hangup support Input: tps65218-pwrbutton - add support for tps65217 variant Input: jornada720_ts - get rid of mach/irqs.h and mach/hardware.h includes Input: jornada720_kbd - remove unneeded mach/hardware.h include Input: focaltech - mark focaltech_set_resolution() static Input: wdt87xx_i2c - fix the flash erase issue Input: gpio-keys-polled - don't use unit-address with button nodes Input: add generic input driver to read encoded GPIO lines Input: add ADC resistor ladder driver Input: pegasus_notetaker - directly include workqueue header Input: elants_i2c - get product id on recovery mode for FW update Input: wm97xx - remove deprecated create_singletheread_workqueue Input: mc13783_ts - remove deprecated create_singletheread_workqueue Input: psmouse - remove deprecated create_singletheread_workqueue Input: jornada720_kbd - switch to using dev_dbg Input: jornada720_kbd - get rid of mach/irqs.h include ...
