Subject: [PATCH 01/12] string: define new memdup_array
Date: Mon, 31 Jan 2022 08:57:14 +0100	[thread overview]
Message-ID: <20220131075725.1873026-2-a.fatoum@pengutronix.de> (raw)
In-Reply-To: <20220131075725.1873026-1-a.fatoum@pengutronix.de>

This will come in handy later for duplicating parent arrays when doing
clock registration.
