Hi Laurent,
I don't want to sound impatient, but I as I don't know what your usual
reaction times to patches are and already waited three weeks without any
reaction, I kindly want to ask, if you already had a chance to look into this
patch and consider it for inclusion into your tree?
Best,
Daniel

Thank you for pinging me, the patch was indeed buried under a pile of other e-
mails :-)
Your mail client (or server, I don't know) mangled the patch by replacing tabs
with spaces. As the patch is short I've fixed this manually, but next time
please try to fix the issue on your side.
Another small issue is that the commit message should be wrapped at 72
columns. Depending on the text editor you use, git commit usually does that
automatically for you.
I've also added a "uvcvideo: " prefix to the subject line, otherwise short git
logs wouldn't be very clear. As a rule of thumb, your subject line should
contain enough information to understand which driver the patch relates to,
and what it does.
Your patch is now in my git tree, and I will push it upstream for v4.13 (v4.11
will be released very soon, and given the pending pull requests for v4.12 in
the Linux media tree I don't think I can add another one).
I collect USB descriptors for UVC devices. Could you please send me the output
of
lsusb -d 05ac:8600
if possible running as root ?
Thank you for your contribution !

Hi Laurent,
I'm really sorry for all the wrong formatting. I already took measures so it
won't happen again.

Thanks a lot. Highly appreciated.

I guess you want the verbose output of lsusb. You'll find it in the attached
file. It might contain more than than you expect as the iBridge device is a
custom ARM processor (probably very similar to the one in the Apple Watch),
not just connecting the webcam to the rest of the system, but also the Touch
Bar and the Touch ID sensor.
Regards,
Daniel
