[PATCH] This adds support for keyboards on mid-2011 MacBook Airs

Hello,

(Please include me explicitly in replies as I'm not subscribed to the list.)

This patch adds proper keyboard support for both MacBook Air 4,1 and 4,2 models (11" and 13" mid-2011 releases). It is based mostly on work by Joshua Dillon.

This fixes the issues with the previously-submitted patch by Pieter-Augustijn Van Malleghem (subject: [PATCH] Add MacBookAir4,1 keyboard support), namely using an incorrect table, and also contains support for both the 4,1 and 4,2 models instead of just the 4,1 model.

Thanks,
Jeff
