The brcmfmac driver spews some error message upon unloading and Stefan
Wahren was wondering whether it could be cleaned up. Related to this
was a recent fix for NULL pointer deref. That fix introduced a construct
that added to the itch to rework the probe sequence. So this series
reverts commit 5cdb0ef6144f ("brcmfmac: fix NULL pointer derefence during
USB disconnect").

The changes in this series are:
 * reorder brcmf_detach() code.
 * avoid firmware interaction when bus is down.
 * remove strlcpy() before issueing firmware version iovar.

This series applies to the master branch of the wireless-drivers-next
repository.
