Merge branch 'for-3.13-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj...

Pull libata fixes from Tejun Heo:
 "libata device removal path was removing parent device node before its
  child, which is mostly harmless but triggers warning after recent
  sysfs changes.  Rafael's patch fixes the order.

  Other than that, minor controller-specific fixes and device ID
  additions"
