Subject: [PATCH 4.18 301/350] media: adv7604: when the EDID is cleared, unconfigure CEC as well
4.18-stable review patch. If anyone has any objections, please let me know.
------------------
From: Hans Verkuil <hans.verkuil@...co.com>
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.
