media: uvcvideo: Move MSXU_CONTROL_METADATA definition to header

2025-09-13T16:34:59+00:00

Move the MSXU_CONTROL_METADATA control definitino to the include/linux/usb/uvc.h header, alongside the corresponding XU GUID. Add a UVC_ prefix to avoid namespace clashes. While at it, add the definition for the other controls for that extension unit, as defined in https://learn.microsoft.com/en-us/windows-hardware/drivers/stream/uvc-extensions-1-5#222-extension-unit-controls.

usb: uvc: use v4l2_fill_fmtdesc instead of open coded format name

2023-01-31T08:40:43+00:00

Since v4l2_fill_fmtdesc will be called in the ioctl v4l_enum_fmt anyway. We can set the format description and compressed flag from v4l_fill_fmtdesc and can remove the extra name field in uvc_format_desc.

usb: uvc: move uvc_fmts and uvc_format_by_guid to own compile unit

2023-01-31T08:40:42+00:00

The media driver USB_VIDEO_CLASS and USB_F_UVC are using the same function uvc_format_by_guid. Since the function is inline, every user will get a copy of the used uvc_fmts array and the function. This patch moves the code to an own compile unit and add this dependency as UVC_COMMON to both users.
