[PARISC] Update harmony from parisc tree
o Added a control for the input source (which can be either "line" or "mic") o Mute the speaker/line-out/headphone outputs by default. o Increased the buffer size from 10 pages to 16. Signed-off-by: Stuart Brady <sdb@parisc-linux.org> ALSA Harmony was resetting the capture position when preparing the capture substream, which it shouldn't do. This should fix the problem. Signed-off-by: Stuart Brady <sdb@parisc-linux.org> ALSA Harmony should no longer play junk (left in the buffers from a previous stream) at the start of a new stream. Implement the monitor mixer channel for ALSA Harmony. Also prevent snd_harmony_volume_get from returning negative values. Signed-off-by: Stuart Brady <sdb@parisc-linux.org> Use the graveyard/silence buffers in ALSA Harmony.
