+
+brcmfmac uses atomic_or() and other atomic_* functions, but does not
+include linux/atomic.h. This file gets included by some other header
+file so this normally does not cause problems.

+Subject: [PATCH] brcmfmac: expose device memory to devcoredump subsystem
+
+Upon PSM watchdog event received from firmware the driver will obtain
+a memory snapshot of the device and expose it to user-space through
+the devcoredump framework. This will trigger a uevent.

+
+When a USB device gets disconnected due to for example removal
+then it is possible that it is still in the loading phase due to
+the asynchronous load routines. These routines can then possible
+access memory which has been freed. Fix this by mutex locking the
+device init phase.

+Subject: [PATCH] brcmfmac: Fix station info rate information.
+
+Txrate and rxrate in get_station got assigned first with value
+in kbps and then divided by 100 to get it in 100kbps unit. The
+problem with that is that type of rate is u16 which resulted
+in incorrect values for high data rate values.
