[PATCH AUTOSEL 4.14 45/95] media: adv7604: when the EDID is cleared, unconfigure CEC as well

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Hans Verkuil <hans.verkuil@xxxxxxxxx>

[ Upstream commit e7da89926f6dc6cf855f5ffdf79ef99a1b115ca7 ]

When there is no EDID the CEC adapter should be unconfigured as
well. So call cec_phys_addr_invalidate() when this happens.
