From 971890f25834e1e81ccb97b9413d0c2852d49208 Mon Sep 17 00:00:00 2001 From: Asai Thambi S P Date: Tue, 29 May 2012 18:41:47 -0700 Subject: [PATCH] mtip32xx: Change HDIO_GET_IDENTITY to return stored data For the ioctl command HDIO_GET_IDENTITY, return the stored copy of IDENTIFY DATA instead of sending the command to the device - similar to libata.
