yeah 2 seconds after i sent the patch i noticed i forgot to remove the
coherent_pool line and i think i sent a v3 with it removed but i will
need to do a v4 and fix what you told me here. and i think i told
fabio that it did not fix the keys however it did allow the kernel to
boot with no panics but the keys still did not work so there is still
something small thats missing or broken in his gpio file i think.

But the patch as is works on 3.6-rc1 with the buttons and leds. If i
get a chance i will try with his patch again later today. Should i
remake the patch on 3.6-rc2 so to be sure it applies cleanly?

Thanks.

p.s Do i send the updated patch directly to you and andrew or to the
list and just cc you both? Still getting used to this mailing list and
submitting a patch thing.
