This is a note to let you know that I've just added the patch titled
gpio: stmpe: pass DT node to irqdomain
to the 3.8-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:
gpio-stmpe-pass-dt-node-to-irqdomain.patch
and it can be found in the queue-3.8 subdirectory.
If you, or anyone else, feels it should not be added to the stable tree,
please let <stable@xxxxxxxxxxxxxxx> know about it.

Subject: gpio: stmpe: pass DT node to irqdomain
From: Gabriel Fernandez <gabriel.fernandez@xxxxxxxxxxxxxx>
commit 9afd9b7090225d78ef56423a2ff65354dc38f1b1 upstream.
The irq domain was implemented but the device tree
node was not transmitted to irq_domain_add_simple().
