A few questions:
Is there any reason for using the global workqueue and not mac80211's workqueue?
Why is the workqueue cancelled in the core_stop callback? Wouldn't it make more
sense to cancel it in bcma_remove/ssb_remove?
This would probably fix the circular dependency. But I'm not entirely sure, because
I'm not that familiar with the code anymore.
