Thanks yeah first time using git first time trying to create a real
patch for linux (and learning how in the process) and trying to figure
out this device tree stuff.

As far as i can tell from looking at the iconnect button definition's
that part is correct (except for the proper codes to do what the
buttons should actually do) the error i get is:

exitcode=0x0000000b


and as for the git command i tried and what it tells me this is what i get:

git send-email --to="alanbutty12 at gmail.com" --smtp-server=Gmail
--no-chain-reply-to --from="alanbutty12 at gmail.com"
/tmp/patches/*.patch


error:
git: 'send-email' is not a git command. See 'git --help'.

I am using a ubuntu 11.10 vm to compile and do my patching and such on
if thats in any way useful.
