Subject: Input: MT - do not apply filtering on emulated events
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=352ce2b0575f195c8e6452a9802e6c186b39409a;p=linux-beck.git

Input: MT - do not apply filtering on emulated events

The pointer emulation events are derived from contact values that
have already been filtered, so send the emulated events as is.
