    ALSA: snd-es1968: Make hardware volume buttons an input device (rev2) · 5a5e02e5
    Hans de Goede authored
    The hardware volume handling code in essence just detects key presses, and
    then does some hardcoded modification of the master volume based on which key
    is pressed.
    
    Clearly the right thing to do here is just report these keypresses to
    userspace and let userspace decide what to with them.
    
    This patch adds a Kconfig option which when enabled reports the volume
    buttons as keypresses using an input device. When enabled this option
    also gets rid of the ugly direct ac97 writes from the tasklet, the ac97lock
    and the need for using a tasklet in general.
