Subject: [PATCH] brcmfmac: change the order of things in brcmf_detach()

When brcmf_detach() from the bus layer upon rmmod we can no longer
|
|
communicate. Hence we will set the bus state to DOWN and cleanup
|
|
the event and protocol layer. The network interfaces need to be
|
|
deleted before brcmf_cfg80211_detach() because the latter does the
|
|
wiphy_unregister() which issues a warning if there are still network
|
|
devices linked to the wiphy instance.
