Why are you exporting these functions if no one calls them?
They are used in the next series, see '[RFC PATCH 04/12] ASoC: SOF:
Intel: add SoundWire configuration interface'
+int hda_sdw_startup(struct snd_sof_dev *sdev)
+{
+ struct sof_intel_hda_dev *hdev;
+ int ret;
+
+ hdev = sdev->pdata->hw_pdata;
+
+ ret = sdw_intel_startup(hdev->sdw);
+ if (ret < 0)
+ return ret;
+ hda_sdw_int_enable(sdev, true);
+
+ return ret;
+}
These 4 functions sdw_intel_acpi_scan, sdw_intel_probe,
sdw_intel_startup and sdw_intel_exit are the interface between the ASoC
world and the Soundwire/Intel module.
I split the patches in two series to make the review and integration
easier on maintainers. The first one is strictly contained within the
driver/soundwire directory while will impact the soundwire and ASoC trees.
