Merge branch 'for-4.2-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/libata
Pull libata fixes from Tejun Heo:
"Three minor device-specific fixes and revert of NCQ autosense added
during this -rc1.
It turned out that NCQ autosense as currently implemented interferes
with the usual error handling behavior. It will be revisited in the
near future"

Revert "libata: Implement NCQ autosense"
