-Subject: [PATCH] mtd: move code adding master MTD out of
- mtd_add_device_partitions()
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-This change is a small cleanup of mtd_device_parse_register(). When
-using MTD_PARTITIONED_MASTER it makes sure a master MTD is registered
-before dealing with partitions. The advantage of this is not mixing
-code handling master MTD with code handling partitions.
-
-This commit doesn't change any behavior except from a slightly different
-failure code path. The new code may need to call del_mtd_device when
-something goes wrong.
