[PATCH AUTOSEL 6.6 07/19] drm/amd/display: Set color_mgmt_changed to true on unsuspend

[Sasha Levin]

From: Joshua Ashton <jos...@froggi.es>

[ Upstream commit 2eb9dd497a698dc384c0dd3e0311d541eb2e13dd ]

Otherwise we can end up with a frame on unsuspend where color management
is not applied when userspace has not committed themselves.

Fixes re-applying color management on Steam Deck/Gamescope on S3 resume.
