Merge branch 'for-4.5' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/libata

Pull libata updates from Tejun Heo:
 "Mostly low level driver specific changes.

  Two changes are somewhat noteworthy.  First, Dan's patchset to support
  per-port msix interrupt handling for ahci, which was tried last cycle
  but had to be backed out due to a couple issues, is back and seems to
  be working fine.  Second, libata exception handling now uses
  usleep_range() instead of msleep() for sleeps < 20ms which can make
  things snappier in some corner cases"
