From 5dd360ebd8328affb22225141cece3a29403b965 Mon Sep 17 00:00:00 2001
From: Daniel Mack <daniel@caiaq.de>

Subject: include/linux/usb/audio-v2.h: add more UAC2 details
Also, remove the 'bmControl' field from uac_clock_selector_descriptor,
which was at the wrong offset. This struct is currently unused.
