V4L/DVB: drivers/media: Use available error codes
In each case, error codes are stored in rc, but the return value is always
0. Return rc 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>
