From fa4453c4c94a61bbefe470b16ddbb6218481c6dc Mon Sep 17 00:00:00 2001 From: Albert Lee Date: Thu, 7 Jun 2007 15:52:07 +0800 Subject: [PATCH] libata passthru: always enforce correct DEV bit Always enforce correct DEV bit since we know which drive the command is targeted. SAT demands to ignore the DEV bit, too.
