Subject: [PATCH] drm/amd/display: Calculate output_color_space after pixel encoding adjustment
Git-commit: 79601b894849cb6f6d6122e6590f1887ac4a66b3
Patch-mainline: v6.2-rc5
References: git-fixes
Code in get_output_color_space depends on knowing the pixel encoding to
determine whether to pick between eg. COLOR_SPACE_SRGB or
COLOR_SPACE_YCBCR709 for transparent RGB -> YCbCr 4:4:4 in the driver.
V2: Fixed patch being accidentally based on a personal feature branch, oops!
Fixes: ea117312ea9f ("drm/amd/display: Reduce HDMI pixel encoding if max clock is exceeded")
