9a887162be USB: uvc_v4l2: cleanup test for end of loop
We're trying to test for the the end of the loop here.  "format" is
never NULL.  We don't know what "format->fcc" is because we're past the
end of the loop and I think "fmt->fmt.pix.pixelformat" comes from the
user so we don't know what that is either.  It works, but it's cleaner
to just test to see if (i == ARRAY_SIZE(uvc_formats).

5d9955f8a9 V4L/DVB: uvc: Fix multiple symbols definitions with UVC gadget and host drivers
The UVC gadget driver borrowed code from the UVC host driver without
changing the symbol names. This results in a namespace clash with
multiple definitions of several symbols when compiling both drivers in
the kernel.

Make all generic UVC functions and variables static in the UVC gadget
driver, as the symbols are not referenced outside of the gadget driver.
Rename the uvc_trace_param global variable to uvc_gadget_trace_param.

cdda479f15 USB gadget: video class function driver
This USB video class function driver implements a video capture device from the
host's point of view. It creates a V4L2 output device on the gadget's side to
transfer data from a userspace application over USB.

The UVC-specific descriptors are passed by the gadget driver to the UVC
function driver, making them completely configurable without any modification
to the function's driver code.
