From 90088bb41200b4da962282dfd45db82544adac3b Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Mon, 9 Oct 2006 11:10:26 +0900 Subject: [PATCH] [PATCH] libata: move ata_irq_on() into libata-sff.c ata_irq_on() isn't used outside of libata core layer. The function is TF/SFF interface specific but currently used by core path with some hack too. Move it from include/linux/libata.h to drivers/ata/libata-sff.c.
