4.2-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Hyungwon Hwang <human.hwang@samsung.com>

commit 65e3293381e1cf1abcfe1aa22b914650a40e3af4 upstream.

After the commit abc0b1447d49 ("drm: Perform basic sanity checks on
probed modes"), proper clock-frequency becomes mandatory for
validating the mode of panel.  The display does not work if there is
no mode validated. Also, this clock-frequency must be set
appropriately for getting required frame rate.

Fixes: abc0b1447d49 ("drm: Perform basic sanity checks on probed modes")
