Subject: [media] drivers/media/usb/tm6000/tm6000-video.c: fix error return code
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=97b55f6a4607cc459da0e857b03f90f3667338f9;p=linux-beck.git

[media] drivers/media/usb/tm6000/tm6000-video.c: fix error return code

Convert a nonnegative error return code to a negative one, as returned
elsewhere in the function.
A simplified version of the semantic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)
// <smpl>
(
if@p1 (\(ret < 0\|ret != 0\))
 { ... return ret; }
|
ret@p1 = 0
)
... when != ret = e1
    when != &ret
*if(...)
{
  ... when != ret = e2
      when forall
 return ret;
}
// </smpl>
