From: Henrik Rydberg Date: Sat, 16 Feb 2013 01:04:03 +0000 (-0800) Subject: Input: synaptics - initialize pointer emulation usage X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=0b85bf78d4aedfdd4bcb1b848045111a5b840310;p=linux-beck.git Input: synaptics - initialize pointer emulation usage To properly setup event parameters for emulated events, pass the appropriate flag to the slot initialization function. Also, all MT-related events should be setup before initialization. Incidentally, this solves the issue of doubly filtered pointer events.
