   4 Subject: [PATCH 16/38] mtd: ubi: add auto_attach HACK for the ASUS RT-AC58U
   5
   6 This patch adds a hack that allows UBI's autoattach feature
   7 to work with the custom ASUS UBI_DEV partition name.
   8
   9 This is necessary because the vendor's u-boot doesn't leave
  10 the bootargs / cmdline alone, so the it can't be overwritten
  11 easily otherwise.
