Subject: [PATCH v2 23/27] video: fbdev: remove unneeded memset after dma_alloc_coherent
Date: Fri, 28 Jun 2019 02:50:17 +0000 [thread overview]
Message-ID: <20190628025019.16026-1-huangfq.daxian@gmail.com> (raw)
In commit af7ddd8a627c
("Merge tag 'dma-mapping-4.21' of git://git.infradead.org/users/hch/dma-mapping"),
dma_alloc_coherent has already zeroed the memory.
So memset is not needed.
