[PATCH v3 0/5] media: uvcvideo: use vb2 ioctl and fop helpers

[Ricardo Ribalda]

This is a rebump of a 4 years old patch from Hans.
https://lore.kernel.org/linux-media/20210618122923.385938-21-ribalda@xxxxxxxxxxxx/

It brings "new" helpers to the uvcdriver and removes tons of code.

The patch:
media: uvcvideo: Refactor uvc_queue_streamon
Is already in the uvc tree. It is here just for CI purposes, do not
review.

I have uploaded my working tree at:
https://gitlab.freedesktop.org/linux-media/users/ribalda/-/commits/b4/uvc-fop
which shows the differences from the original patch, this is mainly for
helping the review to people familiar with the previous patch.
