From 7234592364e2efe8b4ac1040c99b1d7ef01cf502 Mon Sep 17 00:00:00 2001 From: Roland Vossen Date: Mon, 14 Feb 2011 12:16:45 +0100 Subject: staging: brcm80211: removal of inactive d11 code Code cleanup. Removed code that was never invoked because the mac core revision supported is always higher than 22.
