Merge branch 'acpi-enumeration'
* acpi-enumeration: ACPI: remove unnecessary INIT_LIST_HEAD ACPI / platform: include missed header into acpi_platform.c platform / ACPI: Attach/detach ACPI PM during probe/remove/shutdown mmc: sdhci-acpi: add SDHCI ACPI driver ACPI: add SDHCI to ACPI platform devices ACPI / PNP: skip ACPI device nodes associated with physical nodes already i2c / ACPI: add ACPI enumeration support ACPI / platform: Initialize ACPI handles of platform devices in advance ACPI / driver core: Introduce struct acpi_dev_node and related macros ACPI: Allow ACPI handles of devices to be initialized in advance ACPI / resources: Use AE_CTRL_TERMINATE to terminate resources walks ACPI: Centralized processing of ACPI device resources ACPI / platform: Use common ACPI device resource parsing routines ACPI: Move device resources interpretation code from PNP to ACPI core ACPI / platform: use ACPI device name instead of _HID._UID ACPI: Add support for platform bus type ACPI / ia64: Export acpi_[un]register_gsi() ACPI / x86: Export acpi_[un]register_gsi() ACPI: Provide generic functions for matching ACPI device nodes driver core / ACPI: Move ACPI support to core device and driver types
