From: Roland Vossen Date: Mon, 14 Feb 2011 11:16:46 +0000 (+0100) Subject: staging: brcm80211: removed obsolete comments X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=3746507af6c8f7222eafa65188d256b49288ad08;p=linux-beck.git staging: brcm80211: removed obsolete comments Code cleanup. Only mac core revisions 22 and higher are supported, therefore comment related to older mac revisions was removed.
