   4 Subject: [PATCH 02/87] ALSA: hda - Fix the logic to detect VIA analog
   5  low-current mode
   6
   7 commit 924339239fd5ba3e505f9420d41f0939196f3530 upstream.
   8
   9 The analog low-current mode must be enabled when the no stream is
  10 running but the current detection checks it in a wrong way.
