Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input 

Pull input fixes from Dmitry Torokhov:

 - a quirk to i8042 to ignore timeout bit on Lifebook AH544

 - a fixup to Synaptics RMI function 54 that was breaking some Dells

 - a fix for memory leak in soc_button_array driver

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input:
  Input: synaptics-rmi4 - only read the F54 query registers which are used
  Input: i8042 - add Fujitsu Lifebook AH544 to notimeout list
  Input: soc_button_array - fix leaking the ACPI button descriptor buffer
