[4/16] drivers/media/video/zoran: Use available error codes
Commit Message
From: Julia Lawall <julia@diku.dk>
Error codes are stored in res, but the return value is always 0. Return
res 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>
Signed-off-by: Julia Lawall <julia@diku.dk>

This changes the semantics and has not been tested.
