This is a note to let you know that I've just added the patch titled
staging: speakup: avoid out-of-range access in synth_add()
to my staging git tree which can be found at
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging.git
in the staging-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.

Check that array index is in-bounds before accessing the synths[] array.
