Subject: [PATCH] mtd: ubi: block: wire-up device parent
|
|
|
|
ubiblock devices were previously only identifyable by their name, but
|
|
not connected to their parent UBI volume device e.g. in sysfs.
|
|
Properly parent ubiblock device as descendant of a UBI volume device
|
|
to reflect device model hierachy.
