Subject: [PATCH xf86-video-v4l 1/4] Remove unused variable osname
|
||||
|
||||
Coverity is unhappy and there's enough unhappiness in this world already, so
|
||||
let's go for the low-hanging fruit.

|

And expand the size to 18, because the stack array we copied this into is 18
|
||||
bytes long. This covers us for up to 999 (kernel) v4l devices and that is
|
||||
definitely not a reason to use the "640k ought to be enough" meme.
