Subject: [PATCH 6/7] gpio: vf610: Use devres to remove gpiochip
Date:   Sun, 10 Mar 2019 23:27:36 -0700
Message-Id: <20190311062737.6652-7-andrew.smirnov@gmail.com>
In-Reply-To: <20190311062737.6652-1-andrew.smirnov@gmail.com>

Precedence: bulk

Now that the driver's custom remove hook contains only a single
action, replace it by converting the code to use
devm_gpiochip_add_data() to simplify things.
