[PATCH] bind micmute led to capslock led on thinkpads

Hi folks, The attached patch binds the capslock light to the micmute light on my Thinkpad. It works really well. But it's definitely the wrong way to be doing things. There are two problems I'd like to solve a better way: 1) How do I find a pointer to the led_device struct for that led, so that I can call brightness_set on it? 2) How do I hook the kbd_set_leds functions without having to patch atkbd.c? I'm more interested in (1) than (2), but insights on either would be welcome. Thanks! Jason
