[PATCH] IDE: Enable LED support for PowerMac

[Benjamin Herrenschmidt <benh@kernel.crashing.org>]

Hi Bart !

Please submit that to Linus. It adds the Kconfig option for the
PowerMac IDE driver "LED" feature (using the laptop's front LED
as a disk activity indicator). It also adds a small bit to ide-probe.c
that was missing from Jens patch when he added the activity function
infrastructure. He did add the hwif field, but not the code to actually
enable it.

Ben.
