#     Merge tag 'tty-6.0-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty
#     
#     Pull tty/serial driver fixes from Greg KH:
#      "Here are some small tty/serial/vt driver fixes for 6.0-rc4 that
#       resolve a number of reported issues:
#     
#        - n_gsm fixups for previous changes that caused problems
#     
#        - much-reported serdev crash fix that showed up in 6.0-rc1
#     
#        - vt font selection bugfix
#     
#        - kerneldoc build warning fixes
#     
#        - other tiny serial core fixes
#     
#       All of these have been in linux-next for a while with no reported
#       problems"
