drivers/net: Use kcalloc or kzalloc
Use kcalloc or kzalloc rather than the combination of kmalloc and memset.
The semantic patch that makes this change is as follows:
(http://coccinelle.lip6.fr/)
// <smpl>
@@
expression x,y,flags;
statement S;
type T;
@@
x =
- kmalloc
+ kcalloc
(
- y * sizeof(T),
+ y, sizeof(T),
flags);
if (x == NULL) S
-memset(x, 0, y * sizeof(T));
@@
expression x,size,flags;
statement S;
@@
-x = kmalloc(size,flags);
+x = kzalloc(size,flags);
if (x == NULL) S
-memset(x, 0, size);
// </smpl>
