Overview
This function is similar to snd_soc_component_update_bits, but the update operation is scheduled asynchronously. This means it may not be completed when the function returns. To make sure that all scheduled updates have been completed snd_soc_component_async_complete must be called.
Return
1 if the operation was successful and the value of the register changed, 0 if the operation was successful, but the value did not change. Returns a negative error code otherwise.
