Subject: net: alteon: Avoid some useless memset
X-Git-Tag: v5.10.7~1943^2~215
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=721dab2b56535b06f9d5756cf27d875623cb5a60;p=platform%2Fkernel%2Flinux-rpi.git

net: alteon: Avoid some useless memset

Avoid a memset after a call to 'dma_alloc_coherent()'.
This is useless since
commit 518a2f1925c3 ("dma-mapping: zero memory returned from dma_alloc_*")

Replace a kmalloc+memset with a corresponding kzalloc.
