X-Git-Tag: v2.6.37-rc1~64^2~473

V4L/DVB: drivers/media/video/zoran: Use available error codes

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>
