[alsa-devel] [PATCH - pcm_plug] Add details about what pcm_plug does in doc

[olivier at trillion01.com]

From: Olivier Langlois <olivier at trillion01.com>

Current doc only mention conversion to channels, rate and format. It alsa
takes care of access mode mismatch. This is what I was looking for and I
had to look the source code to figure out.
