ALSA: hda - Fix possible runtime PM refcount unbalance
When the driver is unloaded before the codec is bound, it still keeps the runtime PM refcount up, and results in the unbalance. This patch covers these cases by introducing a flag indicating the runtime PM initialization and handling the codec registration procedure more properly. It also fixes the missing input beep device as a gratis, too. Signed-off-by: Takashi Iwai <tiwai@suse.de>
