Subject: [PATCH 0/2] mtd: prepare for dynamically removed devices

Prepare mtd subsystem for devices that can be dynamically removed,
like memory on PCIE card.
Use refcount to prevent crashes when underlying device
removed unexpectedly and reshuffle __get and __put functions
to allow underlying device to clean it memory according to refcount.

Alexander Usyskin (1):
  mtd: call external _get and _put in right order

Tomas Winkler (1):
  mtd: use refcount to prevent corruption
