Merge tag 'upstream-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jgarzik/libata-dev
Pull libata fixes from Jeff Garzik: 1) ahci: Fix typo that caused erronenous error handling. Thought: I wonder if sparse could have caught this, somehow. 2) ahci: support a slightly odd Enmotus variant 3) core: fix a drive detection problem by correcting the logic by which the DevSlp timing variables are obtained and used. * tag 'upstream-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jgarzik/libata-dev: [libata] replace sata_settings with devslp_timing [libata] ahci: Add support for Enmotus Bobcat device. [libata] ahci: Fix lack of command retry after a success error handler.
