Subject: Merge branches 'acpi-scan', 'acpi-utils' and 'acpi-pm'
X-Git-Tag: v3.19-rc1~26^2~3
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=be10f60d29433f712bf0887431efb80975e64438;p=platform%2Fkernel%2Flinux-exynos.git

Merge branches 'acpi-scan', 'acpi-utils' and 'acpi-pm'

* acpi-scan:
  ACPI / scan: Change the level of _DEP-related messages to KERN_DEBUG

* acpi-utils:
  ACPI / utils: Drop error messages from acpi_evaluate_reference()

* acpi-pm:
  ACPI / PM: Do not disable wakeup GPEs that have not been enabled
