Function devm_snd_soc_register_component() allocates a new struct snd_soc_component, adds components and initializes them; since this is also devm, it automatically unregisters components and frees memory upon destruction.
That's exactly what we're doing in the probe function of this driver: switch to that function instead, allowing to remove the last goto and to discard the .remove_new() callback for this driver.
