Bluetooth: Add missing kmalloc NULL tests to Marvell driver
Check that the result of kmalloc is not NULL before dereferencing it. The patch also replaces kmalloc + memset by kzalloc. The semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression *x; identifier f; constant char *C; @@ x = \(kmalloc\|kcalloc\|kzalloc\)(...); ... when != x == NULL when != x != NULL when != (x || ...) ( kfree(x) | f(...,C,...,x,...) | *f(...,x,...) | *x->f ) // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
