From 3d01be72e6fe372a0602221090707a1f04c44646 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Thu, 26 Jul 2012 14:27:39 +0200 Subject: mac80211: don't assume channel is set in tracing With the move to multi-channel and away from drv_config(), hw.conf.channel will not always be set, only for devices using the current API instead of the new channel context APIs. Check the channel is set before adding its frequency to the trace data. Also break some overly long lines in the code.
