[PATCH 16/16] drivers/net/qlcnic: Use available error codes

[Julia Lawall <julia@diku.dk>]

From: Julia Lawall <julia@diku.dk>

The error code is stored in the variable err, but it is the variable ret
that is returned instead.  So store the error code in ret.  Err is then
useless.

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@diku.dk>

This changes the semantics and has not been tested.
