Subject: staging: brcm80211: remove ioctl layer from brcmsmac
X-Git-Tag: next-20111004~7^2~195
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=648f3b75b4688a1107fbfcc5c42005eabff2a3f8;p=karo-tx-linux.git

staging: brcm80211: remove ioctl layer from brcmsmac

The ioctl layer in brcmsmac only provided an interface layer that
was internal to the driver. This is considered pointless and has
been removed.
