[alsa-devel] [PATCH v2 06/13] ASoC: SOF: core: move check for runtime callbacks to core

[Pierre-Louis Bossart]

From: Ranjani Sridharan <ranjani.sridharan at linux.intel.com>

For some platforms, the refcount is explicitly incremented
to prevent it from entering runtime suspend. This
should be be done during probe in the core instead
of being done in the PCM driver.
