Subject: [PATCH] ASoC: mediatek: mt8189: remove unnecessary NULL check

Smatch complains that the call to snd_soc_component_get_drvdata(component)
will dereference "component" so this NULL check is too late.  The probe()
function will never be called with a NULL component pointer so just
delete the check.
