Merge branch 'topic/dummy' into for-linus

    or input, but you may use this module for any application which

    requires a sound card (like RealPlayer).

    pcm_devs       - Number of PCM devices assigned to each card

                     (default = 1, up to 4)

    pcm_substreams - Number of PCM substreams assigned to each PCM

                     (default = 8, up to 16)

    hrtimer        - Use hrtimer (=1, default) or system timer (=0)

    fake_buffer    - Fake buffer allocations (default = 1)

    When multiple PCM devices are created, snd-dummy gives different

    behavior to each PCM device:

      0 = interleaved with mmap support

      1 = non-interleaved with mmap support

      2 = interleaved without mmap 

      3 = non-interleaved without mmap

    As default, snd-dummy drivers doesn't allocate the real buffers

    but either ignores read/write or mmap a single dummy page to all

    buffer pages, in order to save the resouces.  If your apps need

    the read/ written buffer data to be consistent, pass fake_buffer=0

    option.

    The power-management is supported.
