    ALSA: hda - Fix invalid pin powermap without jack detection · 7d10d26d

    commit 7a9744cb upstream.
    
    When a driver is set up without the jack detection explicitly (either
    by passing a model option or via a specific fixup), the pin powermap
    of IDT/STAC codecs is set up wrongly, resulting in the silence
    output.  It's because of a logic failure in stac_init_power_map().
    It tries to avoid creating a callback for the pins that have other
    auto-hp and auto-mic callbacks, but the check is done in a wrong way
    at a wrong time.  The stac_init_power_map() should be called after
    creating other jack detection ctls, and the jack callback should be
    created only for jack-detectable widgets.
    
    This patch fixes the check in stac_init_power_map() and its callee
    at the right place, after snd_hda_gen_build_controls().
