Merge tag 'tty-6.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty
Pull tty/serial driver updates from Greg KH:
"Here is the big set of TTY and Serial driver updates for 6.1-rc1.
Lots of cleanups in here, no real new functionality this time around,
with the diffstat being that we removed more lines than we added!
Included in here are:
- termios unification cleanups from Al Viro, it's nice to finally get
this work done
- tty serial transmit cleanups in various drivers in preparation for
more cleanup and unification in future releases (that work was not
ready for this release)
- n_gsm fixes and updates
- ktermios cleanups and code reductions
- dt bindings json conversions and updates for new devices
- some serial driver updates for new devices
- lots of other tiny cleanups and janitorial stuff. Full details in
the shortlog.
All of these have been in linux-next for a while with no reported
issues"
