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