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.

Both SND_ES1968_INPUT=y and SND_ES1968_INPUT=n work fine on my Dell Inspiron 7000.
