Hi all,
This is V3 and some fixes after Takashi's review.
change between V2-->V3:
- make SND_HDA_I915 selectable
- use snd_printdd to output message
- add return error code check
- use symbol_request to replace symbol_get
- release power_well at azx_free
- some typo fixes
changes between V1-->V2:
- use reference count to track power-well usage
- remove external module, compiled into snd-hda-intel instead
- manage symbols and module loading properly
- remove IS_HSW macro, use flag instead
- remove audio callback for gfx driver to avoid dependency
- split whole patch into two pieces for easy review
- more typo fixes
