[PATCH 3/16] drivers/net/wireless/wl12xx: Use available error codes
From: Julia Lawall
Date: Mon Aug 16 2010 - 12:25:31 EST
From: Julia Lawall <julia@xxxxxxx>
In each case, error codes are stored in ret, but the return value is always
0. Return ret 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@xxxxxxx>

This changes the semantics and has not been tested.
