In commit af7ddd8a627c
("Merge tag 'dma-mapping-4.21' of git://git.infradead.org/users/hch/dma-mapping"),
dmam_alloc_coherent has already zeroed the memory.
So memset is not needed.

It would be better to refer actual commit or commits that implement that
zeroing rather than merge point in commit log if possible.
At quick look commit 518a2f1925c3 ("dma-mapping: zero memory returned
from dma_alloc_*") is the one but I'm not really an expert here to say
is that alone enough.
