From 24fef9022a83d789ee372a393ea4782dc22b9b51 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Thu, 9 Apr 2015 10:28:15 +0200 Subject: [PATCH] ALSA: hda/generic - Don't override power_filter when power_save_node is set Currently the generic parser sets codec->power_filter when power_save_node flag is set. But this overrides the existing filter that has been already set by the codec driver, thus it looses some features. Instead, set the default power_filter only when it's not set yet.
