Subject: [PATCH] mtd: partitions: remove sysfs files when deleting all
master's partitions
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
When support for sysfs "offset" file was added it missed to update the
del_mtd_partitions function. It deletes partitions just like
mtd_del_partition does so both should also take care of removing sysfs
files.
This change moves sysfs_remove_files call to the shared function to fix
this issue.
Fixes: a62c24d755291 ("mtd: part: Add sysfs variable for offset of partition")
