From a2a348014aad8bdf1466e027aa1dad2f099b7de6 Mon Sep 17 00:00:00 2001 From: Vladimir Zapolskiy Date: Mon, 12 Mar 2018 17:06:54 +0100 Subject: video: of: display_timing: Remove of_display_timings_exist() function Since introduction of of_display_timings_exist() function in commit cc3f414cf2e40 ("video: add of helper for display timings/videomode") it didn't attract any users, and the function has no potential, because of_get_display_timings() covers its functionality and does more. Drop the unused exported function from the kernel.
