[alsa-devel] [PATCH 8/8] ASoC: Mark Speyside widgets as ignoring suspend

Allow audio paths through the Speyside system to be kept active while the
system is suspended (for example, when on a voice call) by marking all the
external widgets and the DAI link to the WM1250-EV1 baseband module as
ignoring suspend.
