Hm, that commit seems rather unrelated... is that what git bisect told
you?
I guess my last pull request could be related to that, so maybe you can
check those two commits manually:
077d67374e ("drm: rcar-du: Fix compilation warning")
vs.
0449eefe2d ("drm/fsl-dcu: increment version and date")

It seems that interrupt do not work properly. Could it be that work
elsewhere caused that issue?
