This patch converts the trigger for the LED at the front of Apple's
iBooks to libata. It's merely a replacement of the string ide by disk.
The patch is taken from http://dev.gentoo.org/~josejx/ata.patch. I've
asked Joseph Jezak if he intends to send this patch upstream, but as he
did not reply I'll do so.
The patch needs to be signed off, it cannot be applied otherwise.

You should use -C/-M git options to detect file renames.

Defconfigs should be changed by a separate patch.

This also seems a material for the separate patch. You should first do a
file/function rename and then add support for libata, I think.

Hm, the trigger point seems asymmetric to that one you added to libata.
Here you trigger before executing a request, and in libata after a command
completes; also, in libata you also trigger on ATAPI devices, while here only
on ATA devices...
