2015-04-02[media] gadget/uvc: embed video_deviceHans Verkuil
Embed the video_device struct to simplify the error handling and in order to (eventually) get rid of video_device_alloc/release.

2015-03-02[media] uvc gadget: switch to v4l2 core lockingHans Verkuil
Switch this driver over to the V4L2 core locking mechanism in preparation for switching to unlocked_ioctl. Suggested by Laurent Pinchart. This patch introduces a new mutex at the struct uvc_video level and drops the old mutex at the queue level. The new lock is now used for all ioctl locking and in the release file operation (the driver always has to take care of locking in file operations, the core only serializes ioctls). Note that the mmap and get_unmapped_area file operations no longer take a lock. Commit f035eb4e976ef5a059e30bc91cfd310ff030a7d3 fixed a AB-BA deadlock by moving all the locking down into vb2, so the mmap and get_unmapped_area file operations should no longer do any locking before calling into vb2.

2014-07-16usb: gadget: Gadget directory cleanup - group usb functionsAndrzej Pietrasiewicz
The drivers/usb/gadget directory contains many files. Files which are related can be distributed into separate directories. This patch moves the USB functions implementations into a separate directory. Signed-off-by: Andrzej Pietrasiewicz <andrzej.p@samsung.com> Signed-off-by: Felipe Balbi <balbi@ti.com>
