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>
