[PATCH 0/5] brcmfmac: new device and some fixes

[Arend van Spriel]

This patch series adds new BCM4345 SDIO device support to brcmfmac and
address a number of potential issues either found by testing or code
inspection.

The series is intended for the v4.1 kernel and applies to the master
branch of the wireless-drivers-next repository.

Hante Meuleman (4):
  brcmfmac: Fix oops when SDIO device is removed.
  brcmfmac: Simplify watchdog sleep.
  brcmfmac: Fix possible race-condition.
  brcmfmac: Fix race condition in msgbuf ioctl processing.

Syed Asifful Dayyan (1):
  brcmfmac: Add support for BCM4345 SDIO chipset.

[PATCH 1/5] brcmfmac: Fix oops when SDIO device is removed.

[Arend van Spriel]

From: Hante Meuleman <meuleman@broadcom.com>

On removal of SDIO card both functions of card will be getting
a remove call. When the first is hanging in ctrl frame xmit then
the second will cause oops. This patch fixes the xmit ctrl
handling in case of serious errors and also limits the handling
for remove to function 1 only.

[PATCH 2/5] brcmfmac: Simplify watchdog sleep.

[Arend van Spriel]

From: Hante Meuleman <meuleman@broadcom.com>

The watchdog thread is used to put the SDIO bus to sleep when the
system is idling. This patch simplifies the way it is determined
when sleep can be entered.

[PATCH 3/5] brcmfmac: Fix possible race-condition.

[Arend van Spriel]

From: Hante Meuleman <meuleman@broadcom.com>

SDIO is using a "shared" variable to handoff ctl frames to DPC
and to see when they are done. In a timeout situation this can
lead to erroneous situation where DPC started to handle the ctl
frame while the timeout expired. This patch will fix this by
adding locking around the shared variable.

[PATCH 4/5] brcmfmac: Fix race condition in msgbuf ioctl processing.

[Arend van Spriel]

From: Hante Meuleman <meuleman@broadcom.com>

Msgbuf is using a wait_event_timeout to wait for the response on
an ioctl. The wakeup routine uses waitqueue_active to see if
wait_event_timeout has been called. There is a chance that the
response arrives before wait_event_timeout is called, this
will result in situation that wait_event_timeout never gets
woken again and assumed result will be a timeout. This patch
removes that errornous situation by always setting the
ctl_completed var before checking for queue active.
