Hi,
Please apply this to wireless-dev.

This patch makes sleeping in the hw->config callback possible
by removing the only atomic caller. The atomic caller was
a timer and is replaced by a workqueue.
In general, allowing to sleep in the config callback is a
good thing. bcm43xx must be able to sleep here, as it is
required to lock a mutex.
But there are other good reasons to sleep here. We might
want to sleep for a grace period on channel switch, for example.
Excellent work.
Sleeping in hw->config is a much desired feature for rt2x00 as well,
this is especially beneficial for the USB drivers who always need sleeping.
