This callback will be called by the i915 driver to notify the hda
driver that its HDMI information needs to be refreshed, i e,
that audio output is now available (or unavailable) - usually as a
result of a monitor being plugged in (or unplugged).

ASoC: Updates for v4.3

Not many updates to the core here, but an awful lot of driver updates
this time round:

 - Factoring out of AC'97 reset code into the core
 - New drivers for Cirrus CS4349, GTM601, InvenSense ICS43432, Realtek
   RT298 and ST STI controllers.
 - Machine drivers for Rockchip systems with MAX98090 and RT5645 and
   RT5650.
 - Initial driver support for Intel Skylake devices.
 - A large number of cleanups for Lars-Peter Clausen and Axel Lin.

Use devm_* API to fix leaks in current code.
1. Use devm_kzalloc to fix memory leak for zx_i2s when unload the module.
2. Use devm_snd_soc_register_component to ensure component is unregistered

All the callers assume devm_spear_pcm_platform_register is a devm_ API, so
use devm_snd_dmaengine_pcm_register in devm_spear_pcm_platform_register.

In PCM core, when hw_params() in each driver returns error, the state of
PCM substream is kept as 'open'. In this case, current drivers for sound
units on IEEE 1394 bus doesn't decrement substream counter in hw_free()
correctly. This causes these drivers to keep streams even if not
required.

This commit fixes this bug. When snd_pcm_lib_alloc_vmalloc_buffer()
fails, hw_params function in each driver returns without incrementing the
counter.

A number of functions and structures in the sound subsystem had incomplete
and/or obsolete DocBook comments, leading to warnings when the docs were
built.  Correct those comments so that we can enjoy our audio in the
absence of warning noise.
