2016-03-23ASoC: msm: Use legacy ASM APIs for older targetsAshish Jain
With 3.18 kernel, get_session_time command to DSP is updated to new command. This command is not supported on older targets as they have an older DSP version. To have backwards compatibility, based on DSP version choose which command to use.

2016-03-23xhci-hub: Handle error condition with xhci_stop_deviceMayank Rana
xhci_stop_device() is calling xhci_queue_stop_endpoint() multiple time and doesn't check return value. xhci_queue_stop_endpoint() can return error if xhci is already halted or not able to queue command. xhci_stop_device() waits for stop command completion using wait_for_completion which wouldn't be interrupted or completed if queueing of command fails. It results into possible deadlock condition where usb_disconnect() waits for this udev->lock which is already acquired by caller of xhci_stop_device() which is set_port_feature(). Fix this issue by handling error condition and making sure that xhci_stop_device() doesn't wait if queueing of command is failed.

2016-03-23msm: mdss: dsi: ensure clocks are off when setting their sourceAbhinav Kumar
When DSI panel in unblanked, the driver configures the sources for all the DSI branch clocks based on the current HW configuration. This assumes that the clocks would be off when the panel is unblanked. This may not be true when transitioning to ON state from any of the panel low power states (LP1 or LP2). This can lead to warnings when trying to set the clock source while the clock is enabled. Fix this by ensuring that the clock source is configured only if the panel is not on.

2016-03-23msm: kgsl: Set the DDR high bank bit if specified in the device treeJordan Crouse
On 5XX targets we need to program the bit of the highest DDR bank into a number of registers, one of which is protected which would cause problems if the user mode driver tried to write to it. Specify the high bank bit in the device tree files, set the problematic register in the kernel and then pass the value up to the user mode driver as a property and let them program the other registers. This makes the device tree the authoratative source of the high bit value which is exactly how it should be. If the value isn't specified by the device tree for whatever reason return an error for the property request - that will give the UMD a clue that the value wasn't specified and they should just set a default.
