[PATCH V3 0/1] staging: bcm2835-audio: Add support for simultanous HDMI and Headphone audio

[Michael Zoran]

This is V3 of the change to enable simultanous HDMI and Headphone audio

Changes V2:
        1. Convert to module parameters rather then compile time options
        for configurating which virtual sound card should be loaded.

        2. Remove unnecessary mutex acquire in snd_bcm2835_new_simple_pcm.

        3. Standardize on if (err) instead of if (err < 0).

        4. Multiple minor formating fixes.

Changes V3:
	1. Change the defaults to have the compatible setup the default. Having
	   multiple virtual cards currently doesn't work well with the default
	   audio mixer application in Raspbian.  So perhaps more testing is 
	   needed before this feature should be on by default.

	2. Change the order that the virtual cards load so that if the compability
	   card is enabled, it is always loaded first regardless of which other cards
	   are also loaded.  This appears to increase compatibility with the Raspbian
	   mixer application.

	Note: Even if this feature is not active by default, alot of code was cleaned 
              up in the process.  Other os other then Raspbian can still use it as well
	      and perhaps it would make sense for it to be on by default after it gets
	      tested more.
