Merge tag 'acpi-4.15-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull ACPI fixes from Rafael Wysocki:
"These fix a regression related to the ACPI EC handling during system
suspend/resume on some platforms and prevent modalias from being
exposed to user space for ACPI device object with "not functional and
not present" status.
Specifics:
- Fix an ACPI EC driver regression (from the 4.9 cycle) causing the
driver's power management operations to be omitted during system
suspend/resume on platforms where the EC instance from the ECDT
table is used instead of the one from the DSDT (Lv Zheng).
- Prevent modalias from being exposed to user space for ACPI device
objects with _STA returning 0 (not present and not functional) to
prevent driver modules from being loaded automatically for hardware
that is not actually present on some platforms (Hans de Goede)"
