The current code uses calls from the HDA Codec driver to determine when to suspend/resume by calling hooks via the hda_component binding. However, this means the cs35l41 driver relies on the HDA Codec driver to tell it when to suspend or resume, creating an additional external dependency, and potentially creating race conditions in the future. It is better for the cs35l41 hda driver to decide for itself when the part should be suspended or resumed. This makes supporting system suspend easier.
