ALSA: lola - Changes in proc file
Browse files Browse the repository at this point in the history 
The codec proc file becomes a read only that shows the codec widgets
in a text form.  A new proc file, codec_rw, is introduced instead for
accessing the Lola verb directly by reading and writing to it.

Also, regs proc file shows the contents of DSD, too.
