+Subject: [PATCH] brcmfmac: Update msgbuf read pointer quicker.
+
+On device to host data using msgbuf the read pointer gets updated
+once all data is processed. Updating this pointer more frequently
+allows the firmware to add more data quicker. This will result in
+slightly higher and more stable throughput on CPU bounded host
+processors.

+Subject: [PATCH] brcmfmac: remove watchdog reset from
+ brcmf_pcie_buscoreprep()
+
+The watchdog reset as done in brcmf_pcie_buscoreprep() is not
+sufficient. It needs to modify PCIe core registers as well
+which is properly done by brcmf_pcie_reset_device() after the
+chip recognition is done. So the faulty watchdog reset can be
+removed as it was causing driver reload to fail and hang the
+system requiring a power-cycle. Instead the call to to the
+brcmf_pcie_reset_device() function is done twice in the unload.

+Subject: [PATCH] brcmfmac: have sdio return -EIO when device communication
+ 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
+unload.
