From f8df39f1810b02f877c1ba1eed8e0710019e3b48 Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Thu, 13 May 2010 22:02:03 +0200 Subject: 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/) // @@ expression x,size,flags; statement S; @@ -x = kmalloc(size,flags); +x = kzalloc(size,flags); if (x == NULL) S -memset(x, 0, size); // Signed-off-by: Julia Lawall Acked-by: Gustavo F.
