From 28324304350e23db24d679c55de3f06a5b1e40aa Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Mon, 3 Jul 2006 16:07:26 +0900 Subject: [PATCH] libata: implement ATA_EHI_RESUME_LINK Implement ATA_EHI_RESUME_LINK, which indicates that the link needs to be resumed. This used to be implied by ATA_EHI_HOTPLUGGED. However, hotplug isn't the only event which requires link resume and separating this out allows other places to request link resume. This differentiation also allows better debounce timing selection. This patch converts user scan to use ATA_EHI_RESUME_LINK.
