Staging: 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> Signed-off-by: Julia Lawall <julia@diku.dk>
