Merge tag 'upstream-3.14-rc1' of git://git.infradead.org/linux-ubifs

Pull ubifs updates from Artem Bityutskiy:

 - Improve the NOR erasure quirk - now it tries to do as little writes
   as possible, because the eraseblock may be in an "unstable" state and
   write operation sometimes causes NOR chip lock-ups.

 - Both UBI and UBIFS changes are now maintainer in one single tree,
   because the amount of changes dropped significantly.

* tag 'upstream-3.14-rc1' of git://git.infradead.org/linux-ubifs:
  UBI: avoid program operation on NOR flash after erasure interrupted
  MAINTAINERS: keep UBI and UBIFS stuff in the same tree
  UBI: fix error return code
