Subject: [PATCH 5/5] gpiolib: of: remove [devm_]gpiod_get_from_of_node() APIs
Date: Mon, 19 Dec 2022 11:20:16 -0800	[thread overview]
Message-ID: <20221219192016.1396950-5-dmitry.torokhov@gmail.com> (raw)
In-Reply-To: <20221219192016.1396950-1-dmitry.torokhov@gmail.com>

Now that everyone is using [devm_]fwnode_gpiod_get[_index]() APIs,
remove OF-specific [devm_]gpiod_get_from_of_node().
