serial: 8250: Optimize irq enable after console write (2020-03-27 15:45:54 +0100)
----------------------------------------------------------------
TTY/Serial patches for 5.7-rc1
Here is the big set of TTY / Serial patches for 5.7-rc1
Lots of console fixups and reworking in here, serial core tweaks
(doesn't that ever get old, why are we still creating new serial
devices?), serial driver updates, line-protocol driver updates, and some
vt cleanups and fixes included in here as well.
All have been in linux-next with no reported issues.
