TTY/Serial driver changes for 5.18-rc1
Here are the big set of tty and serial driver changes for 5.18-rc1.
Nothing major, some more good cleanups from Jiri and 2 new serial drivers. Highlights include:
- termbits cleanups
- export symbol cleanups and other core cleanups from Jiri Slaby
- new sunplus and mvebu uart drivers (amazing that people are still creating new uarts...)
- samsung serial driver cleanups
- ldisc 29 is now "reserved" for experimental/development line disciplines
- lots of other tiny fixes and cleanups to serial drivers and bindings
All of these have been in linux-next for a while with no reported issues.
