+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.

+The function chandef_to_chanspec() was not handling 160MHz bandwidth

+Content-Transfer-Encoding: 8bit
+
+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.

+
+When the bus is down, eg. due to rmmod, there is no need to
+attempt to inform firmware about it.

+Subject: [PATCH 7/7] brcmfmac: remove unnecessary strlcpy() upon obtaining
+ "ver" iovar
+
+Recently a strcpy() was replaced by strlcpy(). However, the strcpy()
+was not needed in the first place. So removing that line of code.
