Subject: rt2x00: Remove unneeded variable
X-Git-Tag: v2.6.36-rc1~571^2~107^2~128
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=1ed7a17a8eb4e60b9e25d9d0eaec19ac704d4f9b;p=platform%2Fkernel%2Flinux-3.10.git

rt2x00: Remove unneeded variable

The update_bssid is set only when BSS_CHANGED_BSSID is used,
but the check if that field is true is done later in the function
but also only when BSS_CHANGED_BSSID is set. This makes the
variable useless, as it can never result in a negative check.
