[alsa-devel] [PATCH] ASoC:core:add flag ignore_pmdown_time in snd_soc_dai_link

[ramesh.babu at linux.intel.com]

With this flag, each dai_link in machine driver can choose
to ignore pmdown_time during DAPM shut down sequence.

If the ignore_pmdown_time is set, the DAPM for corresponding DAI
will be executed immediately.
