From: Pierre-Louis Bossart pierre-louis.bossart@linux.intel.com
The bus sdw_drv_remove() and sdw_drv_shutdown() helpers are used conditionally, if the driver provides these routines.
These helpers already test if the driver provides a .remove or .shutdown callback, so there's no harm in invoking the sdw_drv_remove() and sdw_drv_shutdown() unconditionally.
In addition, the current code is imbalanced with dev_pm_domain_attach() called from sdw_drv_probe(), but dev_pm_domain_detach() called from sdw_drv_remove() only if the driver provides a .remove callback.
