From 492b3c0c9c0b1da49890c1954746ce24a2e311f2 Mon Sep 17 00:00:00 2001

Subject: [PATCH 0941/4131] drm/amd/powerplay: remove unnecessary call to
memset
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);
