Hello I've emailed this patch to kernel-team, but have gotten no reply
in a week. I'm not sure whether kernel-team was the correct mailing list
for the patch, so I'm resending it here. This is a trivial patch that
fixes the IR receiver on new Macbooks, allowing the Macs to be
controlled with a remote.
The bug is detailed
here https://bugs.launchpad.net/mactel-support/+bug/157919
Please CC me on replies as I'm not subscribed to this mailing list.
Regards,
Alex
