Merge branch 'upstream-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jgarzik/libata-dev
* 'upstream-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jgarzik/libata-dev: ahci: Add Marvell 6121 SATA support pata_ali: use atapi_cmd_type() to determine cmd type instead of transfer size ahci: implement skip_host_reset parameter ahci: request all PCI BARs devres: implement pcim_iomap_regions_request_all() libata-acpi: improve dock event handling
