Subject: [PATCH v4 00/10] tty: TX helpers

This series introduces uart_port_tx() + uart_port_tx_limited() TX
helpers. See PATCH 8/10 for the details. Comments welcome.

First the series performs simple cleanups, so that the later patches are
easier to follow.

Then it switches drivers to use them. First, to uart_port_tx() in 9/10
and then uart_port_tx_limited() in 10/10.

The diffstat of patches 9+10 is as follows:
 26 files changed, 145 insertions(+), 740 deletions(-)
which appears to be nice.

Jiri Slaby (10):
  tty: serial: move and cleanup vt8500_tx_empty()
  tty: serial: clean up stop-tx part in altera_uart_tx_chars()
  tty: serial: altera_uart_{r,t}x_chars() need only uart_port
  tty: serial: extract lqasc_tx_ready() from lqasc_tx_chars()
  tty: serial: extract tx_ready() from __serial_lpc32xx_tx()
  tty: serial: switch mpc52xx_uart_int_{r,t}x_chars() to bool
  tty: serial: extract serial_omap_put_char() from transmit_chars()
  tty: serial: introduce transmit helpers
  tty: serial: use uart_port_tx() helper
  tty: serial: use uart_port_tx_limited()
