Kai Vehmanen 43bcb1c050 ALSA: hda: do not override bus codec_mask in link_get() ... snd_hdac_ext_bus_link_get() does not work correctly in case there are multiple codecs on the bus. It unconditionally resets the bus->codec_mask value. As per documentation in hdaudio.h and existing use in client code, this field should be used to store bit flag of detected codecs on the bus. By overwriting value of the codec_mask, information on all detected codecs is lost. No current user of hdac is impacted, but use of bus->codec_mask is planned in future patches for SOF.
