This is a note to let you know that I've just added the patch titled
random: use proper return types on get_random_{int,long}_wait()
to the 4.14-stable tree which can be found at:
http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary
The filename of the patch is:
random-use-proper-return-types-on-get_random_-int-long-_wait.patch
and it can be found in the queue-4.14 subdirectory.
If you, or anyone else, feels it should not be added to the stable tree,
please let <stable@xxxxxxxxxxxxxxx> know about it.

Subject: random: use proper return types on get_random_{int,long}_wait()
From: "Jason A. Donenfeld" <Jason@xxxxxxxxx>
commit 7c3a8a1db5e03d02cc0abb3357a84b8b326dfac3 upstream.
Before these were returning signed values, but the API is intended to be
used with unsigned values.
