drivers/net/ax88796.c: Return error code in failure
In this code, 0 is returned on 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>
@a@
identifier alloc;
identifier ret;
constant C;
expression x;
@@
x = alloc(...);
if (x == NULL) { <+... \(ret = -C; \| return -C; \) ...+> }
@@
identifier f, a.alloc;
expression ret;
expression x,e1,e2,e3;
@@
ret = 0
... when != ret = e1
*x = alloc(...)
... when != ret = e2
if (x == NULL) { ... when != ret = e3
return ret;
}
// </smpl>
