ALSA: hda - Add support for more the 8 streams (ccc5df05) · Commits · 戴 / test

In azx_stream_start() and azx_stream_stop(), it use azx_readb/azx_writeb to read/write SIE, it just enable/disable 8 streams. But according to the HDA spec, it support 30 streams, and the new HDA controller will support more then 8 streams. So we should use azx_readl/azx_writel to read/write SIE. Signed-off-by:
