[PATCH 1/3] drivers/net/wimax/i2400m/fw.c: fix error return code

[Julia Lawall <Julia.Lawall@xxxxxxx>]

From: Julia Lawall <Julia.Lawall@xxxxxxx>

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>
@@
identifier ret;
expression e1,e2;
@@

if (ret < 0)
 { ... return ret; }
 ... when != ret = e1
     when forall
*if(...)
 {
  ... when != ret = e2
* return ret;
 }
// </smpl>
