ALSA: hda - Fix bdl_pos_adj value for ATI SB chipsets
ATI SB controllers seem to report the DMA ahead in the amount of FIFO. Thus bdl_pos_adj should be 32 for them as default. Also, the default value is set to -1, which means to make the driver to choose the appropriate value. Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Jaroslav Kysela <perex@perex.cz>
