[PATCH 4.9 21/26] tty: drivers/tty/, stop using tty_schedule_flip()

[Greg Kroah-Hartman]

From: Jiri Slaby <jslaby@xxxxxxx>

commit 5f6a85158ccacc3f09744b3aafe8b11ab3b6c6f6 upstream.

Since commit a9c3f68f3cd8d (tty: Fix low_latency BUG) in 2014,
tty_flip_buffer_push() is only a wrapper to tty_schedule_flip(). We are
going to remove the latter (as it is used less), so call the former in
drivers/tty/.
