Subject: [PATCH v4 3/6] gpio: max77620: Don't set of_node
Date: Thu, 9 Jul 2020 20:12:00 +0300 [thread overview]
Message-ID: <20200709171203.12950-4-digetx@gmail.com> (raw)
In-Reply-To: <20200709171203.12950-1-digetx@gmail.com>
The gpiochip_add_data() takes care of setting the of_node to the parent's
device of_node, hence there is no need to do it manually in the driver's
code. This patch corrects the parent's device pointer and removes the
unnecessary setting of the of_node.
