Dmitry Baryshkov b006aadf72 drm/connector: add mutex to protect ELD from concurrent access ...

[ Upstream commit df7c8e3dde ]

The connector->eld is accessed by the .get_eld() callback. This access
can collide with the drm_edid_to_eld() updating the data at the same
time. Add drm_connector.eld_mutex to protect the data from concurrenct
access. Individual drivers are not updated (to reduce possible issues
while applying the patch), maintainers are to find a best suitable way
to lock that mutex while accessing the ELD data.
