There are some places there saying that the removal will happen at 2.6.39.

-'U' 00-0F drivers/media/video/uvc/uvcvideo.h conflict!
+'U' 00-0F linux/uvcvideo.h conflict!
Please avoid conflicts at userspace API's.

This one seems independent from API changes. Applying it.

Please, don't use "enum" at the public API:
+ __u32 id V4L2 control identifier
+ __u8 name[32] V4L2 control name
+ __u8 entity[16] UVC extension unit GUID
+ __u8 selector UVC control selector
+ __u8 size V4L2 control size (in bits)
+ __u8 offset V4L2 control offset (in bits)
+ enum v4l2_ctrl_type
+ v4l2_type V4L2 control type
+ enum uvc_control_data_type
+ data_type UVC control data type
+ struct uvc_menu_info
+ *menu_info Array of menu entries (for menu controls only)
+ __u32 menu_count Number of menu entries (for menu controls only)
+
+ * struct uvc_menu_info
+
+ __u32 value Menu entry value used by the device
+ __u8 name[32] Menu entry name
enum size is not portable. (OK, I know that V4L2 API has some enum's, but let's
not add new stuff using it). Also, please be sure that the new API won't require
any compat32 bits.
