Merge branch 'for-4.7' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/libata

Browse Source 
Pull libata updates from Tejun Heo:
 "Trivial changes except for special case timeout bumping.

  I have two more libata branches which depend on SCSI and dmaengine
  tree respectively.  I'll send pull requests for them once the
  prerequisite trees are pulled in"

* 'for-4.7' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/libata:
  libata-scsi: use %*ph to dump small buffers
  treewide: Fix typos in libata.xml
  libata-core: Allow longer timeout for drive spinup from PUIS
  libata: Fixup awkward whitespace in warning by removing line continuation.
