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.
