I can't seem to find them in that branch either, and they are not in
linux-next. 

(I seem to have trimmed my original message too much so that the patch
summaries were not included in my reminder. Perhaps you are thinking of
the related mtk-mdp3 fix?)

But I do see an incomplete attempt at a fix of the reference leak in
that branch by someone else in commit cdd0f118ef87 ("media: mediatek:
vcodec: Fix a reference leak in mtk_vcodec_fw_vpu_init()")

Can that commit be dropped in favour of this series or shall I rebase on
top of it?
