[PATCH] ALSA: hda/realtek: Enable front panel headset LED on Lenovo ThinkStation P520

[Hui Wang]

Thanks Kaiheng, and we just had one P520 in the Beijing office and I 
also worked on this issue happenly. Does the led change according to 
jack plugging in or plugging out with your patch? I also prepared a 
patchset but my patchset has more code than yours, please take a look. :-)

Thanks.

Hui.
