Subject: [PATCH 13/17] gpio: max732x: Convert to immutable irq_chip
Date: Thu, 16 Feb 2023 10:37:14 +0100	[thread overview]
Message-ID: <20230215-immutable-chips-v1-13-51a8f224a5d0@linaro.org> (raw)
In-Reply-To: <20230215-immutable-chips-v1-0-51a8f224a5d0@linaro.org>

Convert the driver to immutable irq-chip with a bit of
intuition.
