This doesn't include 9ff8614a3dbe ("brcmfmac: use separate Kconfig file
for brcmfmac") due to a few conflicts with backports changes.
An important change is:
[PATCH 2/7] brcmfmac: change the order of things in brcmf_detach()
which fixes a rmmod crash in the brcmf_txfinalize().

Subject: [PATCH] brcmfmac: use strlcpy() instead of strcpy()
|
||||
|
||||
The function strcpy() is inherently not safe. Though the function
|
||||
works without problems here, it would be better to use other safer
|
||||
function, e.g. strlcpy(), to replace strcpy() still.

Subject: [PATCH 3/3] brcmfmac: allow 160MHz in custom regulatory rules
|
||||
|
||||
The driver has custom regulatory rules which had maximum bandwidth
|
||||
for 5GHz channels set to 80MHz. As a consequence the driver can
|
||||
not use 160MHz in AP mode even when the device supports it. So
|
||||
relax the rules allowing 160MHz. After wiphy_register() the channel
|
||||
flags are updated according what the device actually supports.

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.
