Subject: [PATCH 2/6] video: stm: use DMA_ADDRESS_BROKEN instead of NULL
Date: Mon, 14 Oct 2024 14:58:39 +0200	[thread overview]
Message-ID: <20241014125843.2064532-3-a.fatoum@pengutronix.de> (raw)
In-Reply-To: <20241014125843.2064532-1-a.fatoum@pengutronix.de>

While functionally the same, DMA_ADDRESS_BROKEN marks that the code is
in need of improvement, so it should be used for documentation purposes.
