Merge tag 'tty-4.21-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty
Pull tty/serial driver updates from Greg KH:
"Here is the large TTY/Serial driver set of patches for 4.21-rc1.
A number of small serial driver changes along with some good tty core
fixes for long-reported issues with locking. There is also a new
console font added to the tree, for high-res screens, so that should
be helpful for many.
The last patch in the series is a revert of an older one in the tree,
it came late but it resolves a reported issue that linux-next was
having for some people.
Full details are in the shortlog, and all of these, with the exception
of the revert, have been in linux-next for a while with no reported
issues"
