USB-serial updates for v4.19-rc1
Here are the USB-serial updates for 4.19-rc1, including:
- gpio support for CP2102N devices
- improved line-speed handling for cp210x
- conversion to spin_lock_irqsave() in completion handlers
- dropped kl5kusb105 support from the kl5kusb105 driver (sic!)
Included are also various lower-priority fixes and clean ups.
All but the final commit have been in linux-next, and with no reported
issues.
