that added a warning to media controller core code without updating drivers to comply with the new requirements.

The warning is harmless, drivers will eventually be updated.

Hi Laurant,

1,5 year later this warning still exists in kernel 4.11.

Do you have any guess when this will be fixed?
Can I do anything to help (I am a developer, but not a kernel/driver developer)?

[floe (floe-linux-kernel-bugs)]

This is causing a regression with the Logitech Quickcam Sphere. In particular, the the pan/tilt controls do not work anymore - in fact, they are completely gone from "v4l2-ctl -L".

Same problem with HP TrueVision FHD RGB-IR on HP Spectre x360 13-w013dx

[floe (floe-linux-kernel-bugs)]

Just as a comment, at least in my case this was fixed by the "uvcdynctrl" package which installs suitable udev rules to initialize the missing controls from userspace.

[arthurborsboom (arthurborsboom-linux-kernel-bugs)]

Thanks Florian for the possible workaround. Unfortunately I cannot find a package within Arch Linux providing this uvc userspace tool.

I do notice however that the warnings in Kernel 4.15.1 are still not fixed.
Is this a kernel space (driver) issue or a user space issue ?

[floe (floe-linux-kernel-bugs)]

I think what happened here is that responsibility for initializing the extensions has been shifted from the kernel to userspace. I'd suggest to try and build uvcdynctrl from source and see if that helps...

1. Create a new bug report as yours has almost nothing to do with this one.
2. Perform bisect regression testing.
