Subject: [PATCH] leds: convert IDE trigger to common disk trigger
|

This patch converts the IDE specific LED trigger to a generic disk
|
|
activity LED trigger. The libata core is now a trigger source just
|
|
like before the IDE disk driver. It's merely a replacement of the
|
|
string ide by disk.
|
|
|
|
The patch is taken from http://dev.gentoo.org/~josejx/ata.patch and is
|
|
widely used by any ibook/powerbook owners with great satisfaction.
|
|
Likewise, it is very often used successfully on different ARM platforms.
|
|
|
|
Unlike the original patch, the existing 'ide-disk' trigger is still
|
|
available for backward compatibility. That reduce the amount of patches
|
|
in affected device trees out of the mainline kernel. For further
|
|
development, the new name 'disk-activity' should be used.
