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> Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Signed-off-by: John W. Linville <linville@tuxdriver.com>
