Merge tag 'tty-4.18-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty
Pull tty/serial fixes from Greg KH:
"Here are five fixes for the tty core and some serial drivers.
The tty core ones fix some security and other issues reported by the
syzbot that I have taken too long in responding to (sorry Tetsuo!).
The 8350 serial driver fix resolves an issue of devices that used to
work properly stopping working as they shouldn't have been added to a
blacklist.
All of these have been in linux-next for a few days with no reported
issues"
* tag 'tty-4.18-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty:

serdev: fix memleak on module unload
serial: 8250_pci: Remove stalled entries in blacklist
n_tty: Access echo_* variables carefully.
n_tty: Fix stall at n_tty_receive_char_special().
