Subject: [PATCH 3/3] pinctrl: sh-pfc: Convert to devm_gpiochip_add_data()
Date: Fri, 10 Jun 2016 10:05:03 +0000	[thread overview]
Message-ID: <1465553103-6345-4-git-send-email-geert+renesas@glider.be> (raw)
In-Reply-To: <1465553103-6345-1-git-send-email-geert+renesas@glider.be>

This allows to remove the .remove() callback, and all functions and data
it needed for its own bookkeeping.
