Backport changeset from kernel mainstream

From: Mauro Carvalho Chehab <mchehab@infradead.org>


kernel-sync:

The original patch from Yoann Padioleau <padator@wanadoo.fr>:

Transform some calls to kmalloc/memset to a single kzalloc (or kcalloc).

Here is a short excerpt of the semantic patch performing
this transformation:

@@
type T2;
expression x;
identifier f,fld;
expression E;
expression E1,E2;
expression e1,e2,e3,y;
statement S;
@@

 x =
- kmalloc
+ kzalloc
  (E1,E2)
  ...  when !=
\(x->fld=E;\|y=f(...,x,...);\|f(...,x,...);\|x=E;\|while(...)
S\|for(e1;e2;e3) S\)
- memset((T2)x,0,E1);

@@
expression E1,E2,E3;
@@

- kzalloc(E1 * E2,E3)
+ kcalloc(E1,E2,E3)
