[PATCH v3 0/4] tty: TX helpers

[Jiri Slaby]

This series introduces DEFINE_UART_PORT_TX_HELPER +
DEFINE_UART_PORT_TX_HELPER_LIMITED TX helpers. See PATCH 2/4 for the
details. Comments welcome.

Then it switches drivers to use them. First, to
DEFINE_UART_PORT_TX_HELPER() in 3/4 and then
DEFINE_UART_PORT_TX_HELPER_LIMITED() in 4/4.

The diffstat of patches 3+4 is as follows:
 26 files changed, 191 insertions(+), 823 deletions(-)
which appears to be nice.
