By default 'sdo_limit' is initialized with a default value of '8' as per spec. This is overridden in cases where a different value is required. However this is getting reset when snd_hdac_bus_init_chip() is called again, which happens during runtime PM cycle. Avoid reset by not initializing to default value everytime.

How about to move the default sdo_limit setup into snd_hdac_bus_init() instead? That's the place to be called only once.
thanks,
