I think we need two fixes tag here, one for the RGB array and the other 
one for the RGB+YUV array.

Fixes: 8c16b988ba2d ("drm/msm/dpu: introduce separate wb2_format arrays 
for rgb and yuv")

Fixes: 53324b99bd7b ("drm/msm/dpu: add writeback blocks to the sm8250 
DPU catalog")

(pls ignore the line breaks in the fixes line, I will fix it while applying)
