Subject: [PATCH 4/5] ALSA: hda/generic - Don't override power_filter when power_save_node is set
Date: Thu,  9 Apr 2015 10:40:37 +0200	[thread overview]
Message-ID: <1428568838-21550-5-git-send-email-tiwai@suse.de> (raw)
In-Reply-To: <1428568838-21550-1-git-send-email-tiwai@suse.de>

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.
