+Subject: [PATCH] mtd: move code adding (registering) partitions to the
+ parse_mtd_partitions()
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+This commit slightly simplifies the code. Every parse_mtd_partitions()
+caller (out of two existing ones) had to add partitions & cleanup parser
+on its own. This moves that responsibility into the function.
+
+That change also allows dropping struct mtd_partitions argument.
+
+There is one minor behavior change caused by this cleanup. If
+parse_mtd_partitions() fails to add partitions (add_mtd_partitions()
+return an error) then mtd_device_parse_register() will still try to
+add (register) fallback partitions. It's a real corner case affecting
+one of uncommon error paths and shouldn't cause any harm.
