[PATCH 1/4] media: uvcvideo: uvc_ctrl_is_accessible: check for INACTIVE

[Ricardo Ribalda]

From: Hans Verkuil <hverkuil@xs4all.nl>

Check for inactive controls in uvc_ctrl_is_accessible().
Use the new value for the master_id controls if present,
otherwise use the existing value to determine if it is OK
to set the control. Doing this here avoids attempting to
set an inactive control, which will return an error from the
USB device, which returns an invalid errorcode.

This fixes:

[PATCH 2/4] media: uvcvideo: improve error logging in uvc_query_ctrl()

[Ricardo Ribalda]

From: Hans Verkuil <hverkuil-cisco@xs4all.nl>

If __uvc_query_ctrl() failed with a non-EPIPE error, then
report that with dev_err. If an error code is obtained, then
report that with dev_dbg.

[PATCH 3/4] media: uvcvideo: Return -EACCES for Wrong state error

[Ricardo Ribalda]

For error 2 (Wrong state) return -EACCES instead of -EILSEQ.
EACCES is a much more appropriate error code. EILSEQ will return
"Invalid or incomplete multibyte or wide character." in strerror(),
which is a *very* confusing message.

Re: [PATCH 0/4] Follow-up patches for uvc v4l2-compliance

[Ricardo Ribalda]

Hi James

Thanks for testing the patches. Are you using them on top of linus/master?

Could you send the output of


dmesg -c > /dev/null
v4l2-ctl --all -d /dev/videoX
strace -f v4l2-compliance -d /dev/videoX -E
dmesg


Best regards

Re: [PATCH 0/4] Follow-up patches for uvc v4l2-compliance

[Ricardo Ribalda]

Hi James

That series depends on this v4l2-compliance change:
https://patchwork.linuxtv.org/project/linux-media/patch/20210317143453.483470-1-ribalda@chromium.org/

Could you please apply it and retry?

Thanks!

Thanks for testing it out. In this case I believe that it is a camera

https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/drivers/media/usb/uvc/uvc_driver.c#n766

You might have to send a patch with a quirk for your device.
