There was only one use of __initdata_refok and __exit_refok

__init_refok was used 46 times against 82 for __ref.

Those definitions are obsolete since commit 312b1485fb50 ("Introduce new
section reference annotations tags: __ref, __refdata, __refconst")

This patch removes the following compatibility definitions and replaces
them treewide.

/* compatibility defines */
#define __init_refok     __ref
#define __initdata_refok __refdata
#define __exit_refok     __ref

I can also provide separate patches if necessary.
(One patch per tree and check in 1 month or 2 to remove old definitions)

Pull sound updates from Takashi Iwai:
 "The majority of this update is about ASoC, including a few new
  drivers, and the rest are mostly minor changes.  The only substantial
  change in ALSA core is about the additional error handling in the
  compress-offload API.  Below are highlights:

   - Add the error propagating support in compress-offload API

   - HD-audio: a usual Dell headset fixup, an Intel HDMI/DP fix, and the
     default mixer setup change ot turn off the loopback

   - Lots of updates for ASoC Intel drivers, mostly board support and
     bug fixing, and to the NAU8825 driver

   - Work on generalizing bits of simple-card to allow more code sharing
     with the Renesas rsrc-card (which can't use simple-card due to DPCM)

   - Removal of the Odroid X2 driver due to replacement with simple-card

   - Support for several new Mediatek platforms and associated boards

   - New ASoC drivers for Allwinner A10, Analog Devices ADAU7002,
     Broadcom Cygnus, Cirrus Logic CS35L33 and CS53L30, Maxim MAX8960
     and MAX98504, Realtek RT5514 and Wolfson WM8758"

ACPI 6.0 introduced an optional object _LPI that provides an alternate
method to describe Low Power Idle states. It defines the local power
states for each node in a hierarchical processor topology. The OSPM can
use _LPI object to select a local power state for each level of processor
hierarchy in the system. They used to produce a composite power state
request that is presented to the platform by the OSPM.

Since multiple processors affect the idle state for any non-leaf hierarchy
node, coordination of idle state requests between the processors is
required. ACPI supports two different coordination schemes: Platform
coordinated and  OS initiated.

This patch adds initial support for Platform coordination scheme of LPI.

ACPI 6.0 adds a new method to specify the CPU idle states(C-states)
called Low Power Idle(LPI) states. Since new architectures like ARM64
use only LPIs, introduce ACPI_PROCESSOR_CSTATE to encapsulate all the
code supporting the old style C-states(_CST).

This patch will help to extend the processor_idle module to support
LPI.

This patch enables ACPI_MUTEX_DEBUG for Linux kernel so that the ACPICA
lock order issues can be captured by ACPICA itself.
