Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input
Pull input fixes from Dmitry Torokhov: - a fix for Synaptics touchpads in RMI4 mode failing to suspend/resume properly because I2C client devices are now being suspended and resumed asynchronously which changed the ordering - a change to make sure we do not set right and middle buttons capabilities on touchpads that are "buttonpads" (i.e. do not have separate physical buttons) - a change to zinitix touchscreen driver adding more compatible strings/IDs * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input: Input: psmouse - set up dependency between PS/2 and SMBus companions Input: zinitix - add new compatible strings Input: clear BTN_RIGHT/MIDDLE on buttonpads
