TTY/Serial changes for 7.1-rc1
Here is the set of tty and serial driver changes for 7.1-rc1.
Not much here this cycle, biggest thing is the removal of an old driver
that never got any actual hardware support (esp32), and the second try
to moving the tty ports to their own workqueues (first try was in
7.0-rc1 but was reverted due to problems.)
Otherwise it's just a small set of driver updates and some vt modifier
key enhancements.
All have been in linux-next for a while with no reported issues.
