This is a note to let you know that I've just added the patch titled
net: irda: fix wait_until_sent poll timeout
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-linus 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 hopefully also be merged in Linus's tree for the
next -rc kernel release.
If you have any questions about this process, please let me know.

Subject: net: irda: fix wait_until_sent poll timeout
In case an infinite timeout (0) is requested, the irda wait_until_sent
implementation would use a zero poll timeout rather than the default
200ms.
Note that wait_until_sent is currently never called with a 0-timeout
argument due to a bug in tty_wait_until_sent.
Fixes: 1da177e4c3f4 ("Linux-2.6.12-rc2")
