[PATCH 78/87] wireless: ath10k: remove memset after dma_alloc_coherent
From: Fuqian Huang <hidden>
Date: 2019-06-27 17:45:39
Also in:
linux-wireless, lkml
Subsystem:
atheros ath generic utilities, qualcomm atheros ath10k wireless driver, the rest · Maintainers:
Jeff Johnson, Linus Torvalds
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.
