Commit c13e69b2 authored by Linus Torvalds's avatar Linus Torvalds

Merge tag 'upstream-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jgarzik/libata-dev

Pull libata updates from Jeff Garzik:

 - More ACPI fixes

 - ata_piix: cosmetic code movement, re-enable MS Virtual PC support

 - generic platform driver improvements; use common code

 - pata_cs5536: add quirk for broken udma

 - printk prettiness (dev_printk becomes dev_info, etc.)

 - sata_promise: fix hardreset lockdep error

 - minor cleanups from Sergei Shtylyov

 - minor, automated cleanups from Wei Yongjun

 - fix null ptr deref bug, in sysfs API
