serial: core: Remove BUG_ON(in_interrupt()) check (2021-02-09 11:45:04 +0100)

TTY/Serial driver changes for 5.12-rc1

Here is the big set of tty/serial driver changes for 5.12-rc1.

Nothing huge, just lots of good cleanups and additions:
- Your n_tty line discipline cleanups
- vt core cleanups and reworks to make the code more "modern"
- stm32 driver additions
- tty led support added to the tty core and led layer
- minor serial driver fixups and additions

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