From 967b1307b69b8ada8b331e01046ad1ef83742e99 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Fri, 20 Mar 2015 18:21:03 +0100 Subject: ALSA: hda - Rename power_mgmt flag with power_save_node David suggested that the name "power_mgmt" is too ambiguous. Rename the flag with a bit clearer one "power_save_node". Also, add the corresponding description to HD-Audio.txt, too.
