    Subject[PATCH 4.5 010/124] ALSA: hda - Fix white noise on Asus N750JV headphone
    Date
    4.5-stable review patch.  If anyone has any objections, please let me know.

    ------------------

    From: Bobi Mihalca <bobbymihalca@touchtech.ro>

    commit 9d4dc5840f93bcb002fa311693349deae7702bc5 upstream.

    For reducing the noise from the headphone output on ASUS N750JV,
    call the existing fixup, alc_fixup_auto_mute_via_amp(), additionally.
