   8 commit cae30527901d9590db0e12ace994c1d58bea87fd upstream.
   9
  10 Recently we set CONFIG_SND_HDA_POWER_SAVE_DEFAULT to 1 when
  11 configuring the kernel, then two machines were reported to have noise
  12 after installing the new kernel. Put them in the blacklist, the
  13 noise disappears.
