Agreed, and your shape is cleaner than mine.

Happy to. Noam, are you okay with me carrying your patch in a series?

One question on placement before I write it. Your comment puts the checks after
the frame interval parsing, which is outside the !UVC_FMT_FLAG_COMPRESSED
branch. Frame based formats legitimately carry a zero
dwMaxVideoFrameBufferSize, set unconditionally at uvc_driver.c:265 because the
frame based frame descriptor has no such field, so a zero check there would skip
every frame of a conformant frame based device. Did you mean the checks stay
inside the branch with only the return value changing to -EINVAL, or outside
with an explicit frame based exemption?

I will test the refactor before sending.

The Media CI failure on my patch is the missing dependency on Noam's v2. The
series fixes that.
