Subject: [PATCH] mtd: ubi: wire-up parent MTD device
|
|
|
|
Wire up the device parent pointer of UBI devices to their lower MTD
|
|
device, typically an MTD partition or whole-chip device.
|
|
|
|
The most noticeable change is that in sysfs, previously ubi devices
|
|
would be could in /sys/devices/virtual/ubi while after this change they
|
|
would be correctly attached to their parent MTD device, e.g.
|
|
|
|
/sys/devices/platform/1100d000.spi/spi_master/spi1/spi1.0/mtd/mtd2/ubi0.
|
|
|
|
Locating UBI devices using /sys/class/ubi/ of course still works as
|
|
well.
