---
Changes since V5:
* Fixed warning message reported by kbuild.
* Finalize default register value.
* Update missed AMP_EN register setting during dsm_init.
* Modified SPDEX header style.
Changes since V4:
* Revert return calibration status in max98390_dsm_calib_get:
There is no need to return calibration status in get function
because there is mixer control lock protecting mixer control
access.
And set function of DSM calib finishes calibration
synchronously.
* Fix sprintf in max98390_dsm_init func:
Use snprintf to avoid any unreasonable value from DMI.
Changes since V3:
* Add operation at max98390_dsm_calib_get:
Add cal_running variable at max98390_priv structure
Add return cal_running at max98390_dsm_calib_get
Update cal_running value during calibration
* Update max98390_dsm_init func
Add dsm_param bin name can select upon vendor and product name.
Changes since V2:
* Removed warn massage in max98390_dsm_calib_get func
and add comment.
Changes since V1:
* Updated according to Mark's comments.
* Updated according to Tzung-Bi's comments.
* Removed Enum structure and use TLV data for Volume control
