Subject: rt2x00: Use atomic interface iteration in irq context
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=633257d3db547e7553500f05e0aa2692c876d7a5;p=linux-beck.git

rt2x00: Use atomic interface iteration in irq context

rt2x00lib_beacondone() is called from interrupt context,
this means we cannot use the mac80211 interface iterator
that uses the rtnl lock (since that uses a mutex which can sleep).
Instead we should use the atomic mac80211 interface iterator.
