I cannot find any commits with those hashes.

Should this be

Fixes: 4a352c2fc15a ("drm/msm/dpu: Introduce SC8280XP")
Fixes: 0e91bcbb0016 ("drm/msm/dpu: Add SM8350 to hw catalog")
Fixes: 100d7ef6995d ("drm/msm/dpu: add support for SM8450")

Will wait for a day to fix this up, otherwise I will do it while applying.
