Merge branch 'upstream-linus' of master.kernel.org:/pub/scm/linux/kernel/git/jgarzik/libata-dev
* 'upstream-linus' of master.kernel.org:/pub/scm/linux/kernel/git/jgarzik/libata-dev:
pata_via: Handle laptops via DMI
libata: -ENODEV during prereset isn't an error
libata: don't consider 0xff as port empty if SStatus is available
ata_piix: add short 40c quirk for Acer Aspire 2030, take #2
pata_sis: Fix and clean up some timing setups
hpt3x2n: Correct revision boundary
