[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. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
