#     Merge tag 'tty-5.16-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 5.16-rc1.
#     
#       Nothing major in here at all, just lots of tiny serial and tty driver
#       updates for various reported things, and some good cleanups. These
#       include:
#     
#        - more good tty api cleanups from Jiri
#     
#        - stm32 serial driver updates
#     
#        - softlockup fix for non-preempt systems under high serial load
#     
#        - rpmsg serial driver update
#     
#        - 8250 drivers updates and fixes
#     
#        - n_gsm line discipline fixes and updates as people are finally
#          starting to use it.
#     
#       All of these have been in linux-next for a while now with no reported
#       issues"
