Merge tag 'usb-for-v4.20' of git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-next
Felipe writes:
USB for v4.20
With 63 non-merge commits, this is not a large merge window for USB
peripheral. The largest changes go to the UVC gadget driver which a
few folks have been improving.
Apart from UVC changes, we have a few more devices being added to
Renesas USB3 and DWC3 controller drivers and a couple minor bug fixes
on other drivers.
