[alsa-devel] set power_save_node=0 as default
Hi Takashi,
I measured power consumption between power_save_node=1 and power_save_node=0. It's almost the same. Codec will enter to runtime suspend and suspend. That pin also will enter to D3. Don't need to enter to D3 by single pin. So, Disable power_save_node as default. It will avoid more issues. Windows Driver also has not this option at runtime PM.
Many Thanks.
BR, Kailang

OK, applied now. Thanks.
