Merge branch 'for-4.1' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/libata

Pull libata updates from Tejun Heo:

 - Hannes's patchset implements support for better error reporting
   introduced by the new ATA command spec.

 - the deperecated pci_ dma API usages have been replaced by dma_ ones.

 - a bunch of hardware specific updates and some cleanups.
