| Subject: ALSA: hda - Add two more machines to the power_save_blacklist |
| |
| From: Hui Wang <hui.wang@canonical.com> |
| |
| commit cae30527901d9590db0e12ace994c1d58bea87fd upstream. |
| |
| Recently we set CONFIG_SND_HDA_POWER_SAVE_DEFAULT to 1 when |
| configuring the kernel, then two machines were reported to have noise |
| after installing the new kernel. Put them in the blacklist, the |
| noise disappears. |
