+Subject: [PATCH] brcmfmac: Fix race condition in msgbuf ioctl processing.
+
+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.

+Subject: [PATCH] ath9k_htc: add new WMI_REG_RMW_CMDID command
+
+Since usb bus add extra delay on each request, a command
+with read + write requests is too expensive. We can dramtically
+reduce usb load by moving this command to firmware.
+
+In my tests, this patch will reduce channel scan time
+for about 5-10 seconds.
