Subject: patch "isdn: i4l: Remove ASYNC_CTS_FLOW" added to tty tree


This is a note to let you know that I've just added the patch titled

    isdn: i4l: Remove ASYNC_CTS_FLOW

to my tty git tree which can be found at
    git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty.git
in the tty-next branch.

The patch will show up in the next release of the linux-next tree
(usually sometime within the next 24 hours during the week.)

The patch will also be merged in the next major kernel release
during the merge window.

If you have any questions about this process, please let me know.

Subject: isdn: i4l: Remove ASYNC_CTS_FLOW

ISDN4Linux always enables CTS flow control and does not use the
tty_port_cts_enabled() helper function; remove ASYNC_CTS_FLOW
state enable/disable.
