Merge tag 'tty-5.17-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty
Pull tty/serial driver fixes from Greg KH:
"Here are some small n_gsm and sc16is7xx serial driver fixes for
5.17-rc6.
The n_gsm fixes are from Siemens as it seems they are using the line
discipline and fixing up a number of issues they found in their
testing. The sc16is7xx serial driver fix is for a reported problem
with that chip.
All of these have been in linux-next with no reported problems"
