[PATCH -next 24/27] tty: Prefix tty_ldisc_{lock,lock_nested,unlock} functions

[Peter Hurley]

tty_ldisc_lock(), tty_ldisc_unlock(), and tty_ldisc_lock_nested()
are low-level aliases for the underlying lock mechanism. Rename
with double underscore to allow for new, higher level functions
with those names.
