Subject: [PATCH v2 5/6] commands: of_dump: use of_dup instead of flattening/unflattening
Date: Fri, 19 May 2023 12:01:19 +0200 [thread overview]
Message-ID: <20230519100120.2365970-6-a.fatoum@pengutronix.de> (raw)
In-Reply-To: <20230519100120.2365970-1-a.fatoum@pengutronix.de>
Flattening and unflattening is needlessly laborious. We have of_dup
for that, so let's make use of it.
