From 1ecf9e390452e73a362ea7fbde8f3f0db83de856 Mon Sep 17 00:00:00 2001 From: Daniel Golle Date: Thu, 22 Dec 2022 19:33:04 +0000 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.
