From: Henrik Rydberg Date: Sat, 15 Sep 2012 06:57:18 +0000 (+0200) Subject: Input: MT - Allow legacy pressure computation X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=22739293402966db7ca3eb0148632d986fe30465;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git Input: MT - Allow legacy pressure computation Some drivers like to report ABS_PRESSURE in a special way. Allow this when ABS_MT_PRESSURE is not defined.
