Tested on Trats2 board.

Dear Kukjin,

Could you pull it to current fixes branch (this RC cycle)? The patch
fixes display on Trats2 board. Without it (since abc0b1447d49) it
won't be properly set up and device boots with blank screen and
mentioned error message in logs.

I think this actually is a candidate for stable backporting (4.0+)
because it fixes important functionality of device:

Fixes: abc0b1447d49 ("drm: Perform basic sanity checks on probed modes")
Cc: <stable at vger.kernel.org>
