For all NXP/FSL sound cards using the ASoC architecture this is the case but in case of using the simple-audio-card sound card this isn't the case. In such case the driver probe fails silently and the card isn't available. It took a while to find the missing Kconfig. Make this easier for others by printing a error if this the module isn't available but required by the HW.
