Subject: [PATCH] brcmfmac: include linux/atomic.h
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.

Subject: [PATCH] brcmfmac: Fix race condition between USB probe/load and
disconnect.
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.

When module param p2pon is used a p2p device is created at init.
This patch reworks how this is done by using the same method as
for a dynamically (by user space) created p2p device.

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.
