[alsa-devel] [PATCH/alsa-lib] amixer: fix 'cset' operation to set several channels

[Takashi Sakamoto]

For an enumerated element with several channels, when given comma-separated
string values, 'cset' operation sets these values just to the first channel,
instead of corresponding channels.

This commit adds missing-increment to fix this bug.
