USB: gadget: Return -ENOMEM on memory allocation failure
In this code, 0 is returned on memory allocation failure, even though other failures return -ENOMEM or other similar values. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression ret; expression x,e1,e2,e3; @@ ret = 0 ... when != ret = e1 *x = \(kmalloc\|kcalloc\|kzalloc\)(...) ... when != ret = e2 if (x == NULL) { ... when != ret = e3 return ret; } // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
