Bluetooth: Use kzalloc for drivers
Use 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,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> Acked-by: Gustavo F. Padovan <padovan@profusion.mobi> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
