Subject: KMS: fix EDID detailed timing frame rate
From: Torsten Duwe <torsten@xxxxxx>
commit c19b3b0f6eed552952845e4ad908dba2113d67b4 upstream.
When KMS has parsed an EDID "detailed timing", it leaves the frame rate
zeroed. Consecutive (debug-) output of that mode thus yields 0 for
vsync. This simple fix also speeds up future invocations of
drm_mode_vrefresh().
While it is debatable whether this qualifies as a -stable fix I'd apply
it for consistency's sake; drm_helper_probe_single_connector_modes()
does the same thing already for all probed modes.
