+Subject: [PATCH 16/38] mtd: ubi: add auto_attach HACK for the ASUS RT-AC58U
+
+This patch adds a hack that allows UBI's autoattach feature
+to work with the custom ASUS UBI_DEV partition name.
+
+This is necessary because the vendor's u-boot doesn't leave
+the bootargs / cmdline alone, so the it can't be overwritten
+easily otherwise.
