Given that the GUID is set in uvc_parse_vendor_control() and
uvc_parse_standard_control() for extension units, I'm wo
s after the fw_devlink initialization, so I can still report results.
Before your series:
[0.743065] cpuidle: using governor menu
[ 13.350259] No ATAGs?
With your series applied:
[ 0.722670] cpuidle: using governor menu
[1.135859] No ATAGs?
That's a very clear improveme

No need for a blank line.
And it looks like the local irq variable should be introduced in this
patch, not in the previous one. I think I'd squash this with 5/6.

I'm not an expert in this domain, but before investigating it, would you
be able to share a hack patch that implements this (in the most simple
way) to check if it actually fixes the delays I experience on my system

I'd turn this into a dev_dbg(), printing error messages to the kernel
log in response to user-triggered conditions is a bit too verbose and
could flood the log.
Wouldn't it be best to catch this issue when creating the framebuffer ?

us either adjust or reset
the crop and selection rectangles. The specification isn't clear on
which behaviour should be implemented, the only related text is
"Sub-devices that scale frames using variable scaling factors should
reset the scale factors to default values when sink pads formats are
modified. If the 1:1 scaling ratio is supported, this means that source
pads formats should be reset to the sink pads formats."
I would recommend resetting as the default behaviour. In any case,
adjustements are needed to ensure that the configuration remains valid.

path and in remove().
On the other hand, not setting .bus_type and letting the parse()
function determine the but type automatically is also deprecated, and I
don't think forcing drivers to call v4l2_fwnode_endpoint_alloc_parse()
once for each bus type until one succeeds is a good API. As
