[alsa-devel] [PATCH] ASoC: Ensure supplies are maintained for force enabled widgets

[Mark Brown]

If a widget has been force enabled then not only do we need to keep the
widget itself enabled, we also need to keep any supplies the widget
requires enabled. The user could force all the individual widgets on but
this requires too much knowledge of device internals.

This is only compile tested so far.
