Merge tag 'tty-5.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty

Pull tty/serial updates from Greg KH:
 "Here is the big set of tty and serial driver patches for 5.10-rc1.

  Lots of little things in here, including:

   - tasklet_setup api conversions

   - sysrq support for capital letters

   - vt and vc cleanups and unwinding the mess some more

   - serial driver updates and minor tweaks

   - new device ids

   - rs485 support for some drivers

   - serial binding documentation updates

   - lots of small serial driver changes for reported issues

  All have been in linux-next for a while with no reported issues"
