    ALSA: hda - Let all conexant codec enter D3 when rebooting · 9585f444

    commit 401714d9534aad8c24196b32600da683116bbe09 upstream.
    
    We have 3 new lenovo laptops which have conexant codec 0x14f11f86,
    these 3 laptops also have the noise issue when rebooting, after
    letting the codec enter D3 before rebooting or poweroff, the noise
    disappers.
    
    Instead of adding a new ID again in the reboot_notify(), let us make
    this function apply to all conexant codec. In theory make codec enter
    D3 before rebooting or poweroff is harmless, and I tested this change
    on a couple of other Lenovo laptops which have different conexant
    codecs, there is no side effect so far.
