#     
#     Pull tty/serial fixes from Greg KH:
#      "Here are some small tty and serial core fixes for 6.5-rc7 that resolve
#       a lot of reported issues.
#     
#       Primarily in here are the fixes for the serial bus code from Tony that
#       came in -rc1, as it hit wider testing with the huge number of
#       different types of systems and serial ports. All of the reported
#       issues with duplicate names and other issues with this code are now
#       resolved.
#     
#       Other than that included in here is:
#     
#        - n_gsm fix for a previous fix
#     
#        - 8250 lockdep annotation fix
#     
#        - fsl_lpuart serial driver fix
#     
#        - TIOCSTI documentation update for previous CAP_SYS_ADMIN change
#     
#       All of these have been in linux-next for a while with no reported
#       problems"
