Merge tag 'spi-fix-v4.14-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/brooni...

Pull spi fixes from Mark Brown:
 "There are a bunch of device specific fixes (more than I'd like, I've
  been lax sending these) plus one important core fix for the conversion
  to use an IDR for bus number allocation which avoids issues with
  collisions when some but not all of the buses in the system have a
  fixed bus number specified.

  The Armada changes are rather large, specificially "spi: armada-3700:
  Fix padding when sending not 4-byte aligned data", but it's a storage
  corruption issue and there's things like indentation changes which
  make it look bigger than it really is. It's been cooking in -next for
  quite a while now and is part of the reason for the delay"
