Subject: [PATCH 08/15] ARM: i.MX bbu-external-nand: Do not modify image
Date: Mon, 17 May 2021 20:54:17 +0200 [thread overview]
Message-ID: <20210517185424.32145-9-s.hauer@pengutronix.de> (raw)
In-Reply-To: <20210517185424.32145-1-s.hauer@pengutronix.de>
struct bbu_data::image is const, so do not modify the image, but create
a copy instead.
