From 8f0972dfa9b7378aaf14eebf2454abd93a6033ad Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Mon, 27 Jan 2014 16:26:16 +0100 Subject: [PATCH] ALSA: hda - Avoid unnecessary verbs write in snd_hda_activate_path() ... by using snd_Hda_codec_update_cache() instead of *_write_cache(). Since all path elements should have been updated by this function, we are safe to assume that the cache contents are consistent.
