Subject: [PATCH v2 14/27] mtd: nand: use kzalloc instead of kmalloc and memset
Date: Fri, 28 Jun 2019 10:48:13 +0800 [thread overview]
Message-ID: <20190628024814.15527-1-huangfq.daxian@gmail.com> (raw)
Replace kmalloc followed by a memset with kzalloc.
There is a recommendation to use zeroing allocator
rather than allocator followed by memset with 0 in
./scripts/coccinelle/api/alloc/zalloc-simple.cocci
