4.9-stable review patch. If anyone has any objections, please let me know.
------------------
From: Chen-Yu Tsai <w...@csie.org>
commit 230c5b44233ff0543c0b5ccf4ff9400057010fbe upstream.
In the loop on .timings, we should check .num_timings to see if it's the
only mode specified, not .num_modes, which should be used with .modes.
Fixes: cda553725c92 ("drm/panel: simple: Set appropriate mode type")
