Subject: qed: remove unnecessary call to memset
Patch-mainline: v4.14-rc1
Git-commit: 4739df6211911e6597602222b640e5c002563df6
References: bsc#1050536 FATE#322898

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);
