Merge tag 'usb-4.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb
Pull USB/PHY updates from Greg KH:
"Here is the big USB and phy driver patch set for 4.19-rc1.
Nothing huge but there was a lot of work that happened this
development cycle:
- lots of type-c work, with drivers graduating out of staging, and
displayport support being added.
- new PHY drivers
- the normal collection of gadget driver updates and fixes
- code churn to work on the urb handling path, using irqsave()
everywhere in anticipation of making this codepath a lot simpler in
the future.
- usbserial driver fixes and reworks
- other misc changes
All of these have been in linux-next with no reported issues for a
while"
