ALSA: hda: Fix a mask wrong issue in snd_hdac_stream_start()
Browse files Browse the repository at this point in the history
To enable SIE(Stream Interrupt Enable) in snd_hdac_stream_start(), we
should set both mask and value to be "1 << azx_dev->index" for register
update, the mask was 0, here fix it.
