Ian Schram 3a33cc108d mac80211_hwsim.c: fix: BUG: unable to handle kernel NULL pointer dereference at 0000000000000370 
I was looking at this out of interest, but I'm in no way familiar with
the code.

Looks to me that the error handling code in mac80211_hwsim is awkward.
Which leads to it calling ieee80211_unregister_hw even when
ieee80211_register_hw failed.

The function has a for loop where it generates all simulated radios.
when something fails, the error handling will call mac80211_hwsim_free
which frees all simulated radios who's pointer isn't zero. However the
information stored is insufficient to determine whether or not the call
to ieee80211_register_hw succeeded or not for a specific radio. The
included patch makes init_mac80211_hwsim clean up the current simulated
radio, and then calls into mac80211_hwsim_free to clean up all the
radios that did succeed.

This however doesn't explain why the rate control registration failed..
build tested this, but had some problems reproducing the original
problem.
