From eadd33bb95e0ab5e3f443bcd9ca45af4010110c8 Mon Sep 17 00:00:00 2001 From: Tomi Valkeinen Date: Thu, 5 Jun 2014 11:36:08 +0300 Subject: OMAPDSS: DISPC: clean up dispc_mgr_timings_ok dispc_mgr_timings_ok() is a bit confusing how it handles the return value. Change the function to just return immediately when a timing is deemed not valid, making the code much easier to follow.
