This is a note to let you know that I've just added the patch titled
staging/fbtft: Depend on OF
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.

Commit c440eee1a7a1 ("Staging: fbtft: Switch to the gpio descriptor interface") removed setting gpios via platform data. This means that fbtft will now only work with Device Tree so set the dependency.
This also prevents a NULL pointer deref on non-DT platform because fbtftops.request_gpios is not set in that case anymore.
