   4 Subject: [PATCH] mtd: partitions: remove sysfs files when deleting all
   5  master's partitions
   6 MIME-Version: 1.0

  10 When support for sysfs "offset" file was added it missed to update the
  11 del_mtd_partitions function. It deletes partitions just like
  12 mtd_del_partition does so both should also take care of removing sysfs
  13 files.
  14
  15 This change moves sysfs_remove_files call to the shared function to fix
  16 this issue.

  18 Fixes: a62c24d755291 ("mtd: part: Add sysfs variable for offset of partition")
