4.19-stable review patch. If anyone has any objections, please let me know.
------------------ From: Hans Verkuil <[email protected]> commit e7da89926f6dc6cf855f5ffdf79ef99a1b115ca7 upstream. When there is no EDID the CEC adapter should be unconfigured as well. So call cec_phys_addr_invalidate() when this happens.
