Merge branch 'depends/tty' into next/headers
Merging in Greg's tty tree including a cleanup patch needed by the OMAP serial
header cleanups.
* depends/tty: (305 commits)
tty/serial/8250: Make omap hardware workarounds local to 8250.h
serial/8250/8250_early: Prevent rounding error in uartclk
serial: samsung: use clk_prepare_enable and clk_disable_unprepare
TTY: Report warning when low_latency flag is wrongly used
console: use might_sleep in console_lock
TTY: move tty buffers to tty_port
TTY: add port -> tty link
TTY: tty_buffer, cache pointer to tty->buf
TTY: move TTY_FLUSH* flags to tty_port
TTY: n_tty, propagate n_tty_data
TTY: move ldisc data from tty_struct: locks
TTY: move ldisc data from tty_struct: read_* and echo_* and canon_* stuff
TTY: move ldisc data from tty_struct: bitmaps
TTY: move ldisc data from tty_struct: simple members
TTY: n_tty, add ldisc data to n_tty
TTY: audit, stop accessing tty->icount
TTY: n_tty, remove bogus checks
TTY: n_tty, simplify read_buf+echo_buf allocation
