Subject: [PATCH v2 0/2] mtd: mtdconcat: Fix callback functions check

Patch 1: Check subdev's master mtd device's callback function while
making concatenated device.
Patch 2: Check existence of _read|_write callback before assigning
them to concatenated device.

v1->v2:
  Shorten two commit titles.
  Patch 1: Add comment to explain why datamember checks for subdev
           but callbacks checks for master device
  Patch 1: Fix misspelled word, "comnoine fail" -> "combine failed"
  Patch 2: Fix wrong commit message, "Since ... time. We should"
  Patch 2: Check against the existence of _read|_read_oob callbacks
           by master, no removing concat_{read|write}_oob.

Zhihao Cheng (2):
  mtd: mtdconcat: Judge callback existence based on the master
  mtd: mtdconcat: Check _read,_write callbacks existence before
    assignment
