+Subject: [PATCH] brcmfmac: Build wiphy mode and interface combinations
+ dynamically
+
+Switch from using semi hard coded interface combinations. This makes
+it easier to announce what the firmware actually supports. This fixes
+the case where brcmfmac announces p2p but the firmware doesn't
+support it.

+Subject: [PATCH] brcmfmac: rework .get_station() callback
+
+The .get_station() cfg80211 callback is used in several scenarios. In
+managed mode it can obtain information about the access-point and its
+BSS parameters. In managed mode it can also obtain information about
+TDLS peers. In AP mode it can obtain information about connected
+clients.

+Subject: [PATCH] ath9k: make DMA stop related messages debug-only
+
+A long time ago, ath9k had issues during reset where the DMA engine
+would stay active and could potentially corrupt memory.
+To debug those issues, the driver would print warnings whenever they
+occur.
+
+Nowadays, these issues are gone and the primary cause of these messages
+is if the MAC is stuck during reset or busy processing a long
+transmission. This is fairly harmless, yet these messages continue to
+worry users.
+
+To reduce the number of bogus bug reports, turn these messages into
+debug messages and count their occurence in the "reset" debugfs file.

- is not possible
-
-The bus interface functions txctl and rxctl may be used while the device
-can not be accessed, eg. upon driver .remove() callback. This patch will
-immediately return -EIO when this is the case which speeds up the module

-Subject: [PATCH] ath9k: make DMA stop related messages debug-only
-
-A long time ago, ath9k had issues during reset where the DMA engine
-would stay active and could potentially corrupt memory.
-To debug those issues, the driver would print warnings whenever they
-occur.
-
-Nowadays, these issues are gone and the primary cause of these messages
-is if the MAC is stuck during reset or busy processing a long
-transmission. This is fairly harmless, yet these messages continue to
-worry users.
-
-To reduce the number of bogus bug reports, turn these messages into
-debug messages and count their occurence in the "reset" debugfs file.
