+Subject: [PATCH] brcmfmac: Fix oops when SDIO device is removed.
+
+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.

+
+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.

+Subject: [PATCH] brcmfmac: Fix possible race-condition.
+
+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.

+The firmware provides pointer to SDIO shared information at end of

+
+The watchdog timer is used to put the device in a low-power mode when
+it is idle for some time. This timer is stopped during that mode and
+should be restarted upon activity. This has been broken by commit
+d4150fced0365 ("brcmfmac: Simplify watchdog sleep."). This patch
+restores the behaviour as it was before that commit.

+Subject: [PATCH] brcmfmac: avoid runtime-pm for sdio host controller
+
+Several host controllers supporting runtime-pm are causing issues
+with our sdio wireless cards because they disable the sdio interrupt
+upon going into runtime suspend. This patch avoids that by doing
+a pm_runtime_forbid() call during the probe. Tested with Sony Vaio
+Duo 13 which uses sdhci-acpi host controller.

+Subject: [PATCH] brcmfmac: only support the BCM43455/7 device
+
+Recently support was added for the BCM4345 SDIO chipset by
+commit 9c51026509d7 ("brcmfmac: Add support for BCM4345 SDIO chipset")
+however this was verified using a BCM43455 device, which is
+a more recent revision of the chip. This patch assure that
+older revisions are not probed as they would fail.

+The BCM43362 firmware falsely reports it is capable of providing
