From: Arik Nemtsov Date: Mon, 26 May 2014 11:40:51 +0000 (+0300) Subject: mac80211: don't check netdev state for debugfs read/write X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=c7e592387547f09a0e25a698f9295edec03971d8;p=karo-tx-linux.git mac80211: don't check netdev state for debugfs read/write commit 923eaf367206e01f22c97aee22300e332d071916 upstream. Doing so will lead to an oops for a p2p-dev interface, since it has no netdev.
