Julia Lawall 3053814c1c V4L/DVB: drivers/media/video: Use available error codes 
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 ...;
)
}
