Subject: [PATCH v17 2/3] mtd: Move struct mtd_concat definition to header file
Date: Wed, 04 Feb 2026 09:32:17 +0100 [thread overview]
Message-ID: <20260204-mtd-virt-concat-v17-2-5e98239bb55b@bootlin.com> (raw)
In-Reply-To: <20260204-mtd-virt-concat-v17-0-5e98239bb55b@bootlin.com>
From: Amit Kumar Mahapatra <amit.kumar-mahapatra@amd.com>
To enable a more generic approach for concatenating MTD devices,
struct mtd_concat should be accessible beyond the mtdconcat driver.
Therefore, the definition is being moved to a header file.
