Subject: [PATCH] mwifiex: remove unnecessary call to memset
Git-commit: 85dafc12919659ec744e111b1714792cd3d0a9ca
Patch-mainline: v4.15-rc1
References: FATE#326294
call to memset to assign 0 value immediately after allocating
memory with kzalloc is unnecesaary as kzalloc allocates the memory
filled with 0 value.
Semantic patch used to resolve this issue:
@@
expression e,e2; constant c;
statement S;
@@
e = kzalloc(e2, c);
if(e == NULL) S
- memset(e, 0, e2);
