There's already a 05a9:2643 webcam model, found in a Dell monitor, that has
been reported to work properly without the UVC_QUIRK_PROBE_DEF. Enabling the
quirk shouldn't hurt, but I'd like to check differences between the two
devices. Could you please send me the output of

lsusb -v -d 05a9:2643

(running as root if possible) ?

Your mailer messed up formatting. As the patch is small I've fixed it
manually, but please make sure to use a proper mail client next time. I advise
using git-send-email to send patches.
