net/ax25: Use available error codes
Error codes are stored in err, but the return value is always 0. Return
err instead.
The semantic match that finds this problem is as follows:
(http://coccinelle.lip6.fr/)
// <smpl>
@r@
local idexpression x;
constant C;
@@
if (...) { ...
x = -C
... when != x
(
return <+...x...+>;
|
return NULL;
|
return;
|
* return ...;
)
}
// </smpl>
