Subject: [PATCH v2] gpio: visconti: Fix fwnode of GPIO IRQ
Date:   Thu, 21 Apr 2022 18:42:28 +0900
Message-Id: <20220421094228.2141569-1-nobuhiro1.iwamatsu@toshiba.co.jp>
MIME-Version: 1.0

Precedence: bulk

The fwnode of GPIO IRQ must be set to its own fwnode, not the fwnode of the
parent IRQ. Therefore, this sets own fwnode instead of the parent IRQ fwnode to
GPIO IRQ's.

Fixes: 2ad74f40dacc ("gpio: visconti: Add Toshiba Visconti GPIO support")
