USB-serial updates for 5.13-rc1
Here are the USB-serial updates for 5.13-rc1, including:
- better type detection for pl2303
- support for more line speeds for pl2303 (TA/TB)
- fixed CSIZE handling for the new xr driver
- core support for multi-interface functions
- TIOCGSERIAL and TIOCSSERIAL fixes
- generic TIOCSSERIAL support (e.g. for closing_wait)
- fixed return value for unsupported ioctls
- support for gpio valid masks in cp210x
- drain-delay fixes and improvements
- support for multi-port devices for xr
- generalisation of the xr driver to support three new device classes
(XR21B142X, XR21B1411 and XR2280X)
Included are also various clean ups.
All have been in linux-next with no reported issues.
