Subject: [PATCH 45/87] fbdev: mmp: remove memset after dma_alloc_coherent in mmpfb.c
Date: Thu, 27 Jun 2019 17:41:09 +0000 [thread overview]
Message-ID: <20190627174110.4345-1-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.
