TTY/Serial fixes for 5.12-rc3

Here are some small tty and serial driver fixes for 5.12-rc3 to resolve
some reported problems:
	- led tty trigger fixes based on review and were acked by the
	  led maintainer
	- revert a max310x serial driver patch as it was causing
	  problems.
	- revert a pty change as it was also causing problems

All of these have been in linux-next for a while with no reported
problems.
