commit 79601b894849cb6f6d6122e6590f1887ac4a66b3 upstream.
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!
