    Subject[PATCH 5.0 057/117] ALSA: hda - Add two more machines to the power_save_blacklist
    Date
    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.
