X-Git-Tag: firefly_0821_release~7613^2~3670^2~679^2~39
X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=36d344131c154c0fb7dd6a3703fc1b29c56a75a1;p=firefly-linux-kernel-4.4.55.git

drivers/net/wireless/wl12xx: Use available error codes

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>
