Subject: [PATCH 07/16] gpio: Move irq_chained_parent to struct gpio_irq_chip
Date: Fri, 1 Sep 2017 20:57:27 +0200 [thread overview]
Message-ID: <20170901185736.28051-8-thierry.reding@gmail.com> (raw)
In-Reply-To: <20170901185736.28051-1-thierry.reding@gmail.com>
From: Thierry Reding <treding@nvidia.com>
In order to consolidate the multiple ways to associate an IRQ chip with
a GPIO chip, move more fields into the new struct gpio_irq_chip.
Signed-off-by: Thierry Reding <treding@nvidia.com>
