-From: Daniel Golle <daniel@makrotopia.org>
-Subject: libata: add ledtrig support
-
-This adds a LED trigger for each ATA port indicating disk activity.
-
-As this is needed only on specific platforms (NAS SoCs and such),
-these platforms should define ARCH_WANTS_LIBATA_LEDS if there
-are boards with LED(s) intended to indicate ATA disk activity and
-need the OS to take care of that.
-In that way, if not selected, LED trigger support not will be
-included in libata-core and both, codepaths and structures remain
-untouched.
