[ Upstream commit ae861c466ee57e15a29d97629e1c564e3f714a4f ]
The cs35l56->component pointer is used by the suspend-resume handling to know whether the driver is fully instantiated. This is to prevent it queuing dsp_work which would result in calling wm_adsp when the driver is not an instantiated ASoC component. So this pointer must be cleared by cs35l56_component_remove().
