Subject: [PATCH] HID: multitouch: Synchronize MT frame on reset_resume
Date: Tue, 29 Mar 2016 22:10:41 +0200 [thread overview]
Message-ID: <1459282241-25154-1-git-send-email-gabriele.mzt@gmail.com> (raw)
input_mt_get_slot_by_key() requires input_mt_sync_frame() to be called
at each frame. Do it when releasing the touches, or else we won't get
a proper slot number after mt_reset_resume().
