From 0cbf0711a1ebcc4d3aea8e11def684afc2c07ef8 Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Mon, 19 May 2008 01:15:05 +0900 Subject: [PATCH] libata: fix sata_link_hardreset() @online out parameter handling The @online out parameter is supposed to set to true iff link is online and reset succeeded as advertised in the function description and callers are coded expecting that. However, sata_link_reset() didn't behave this way on device readiness test failure. Fix it.
