This patch series is improving the size calculation and allocation of
the uvc requests. Using the selected frame duration of the stream it is
possible to calculate the number of requests based on the interval
length.
It also precalculates the request length based on the actual per frame
size for compressed formats.
For this calculations to work it was needed to rework the request
queueing by moving the encoding to one extra thread (in this case we
chose the qbuf) context.
Next it was needed to move the actual request enqueueing to one extra
thread which is kept busy to fill the isoc queue in the udc.

Changes in v6:
- fixes in: ("usb: gadget: uvc: add trace of enqueued and completed requests")
- Link to v5: https://lore.kernel.org/r/20240403-uvc_request_length_by_interval-v5-0-2de78794365c@xxxxxxxxxxxxxx
Breaks the build for me:
In file included from drivers/usb/gadget/function/uvc_trace.h:60,
from drivers/usb/gadget/function/uvc_trace.c:11:

what did you build this against?
