drivers/net/wireless/ipw2x00/ipw2100.c: introduce missing initialization
The result of one call to a function is tested, and then at the second call
to the same function, the previous result, and not the current result, is
tested again.
Also changed &bssid to bssid, at the suggestion of Stanislav Yakovlev.
The semantic match that finds the first problem is as follows:
(http://coccinelle.lip6.fr/)
// <smpl>
@@
expression ret;
identifier f;
statement S1,S2;
@@
*ret = f(...);
if (\(ret != 0\|ret < 0\|ret == NULL\)) S1
... when any
*f(...);
if (\(ret != 0\|ret < 0\|ret == NULL\)) S2
// </smpl>
