From f1cb0ea12fee23018ad1865bf789cbd463f13747 Mon Sep 17 00:00:00 2001 From: Saeed Bishara Date: Mon, 18 Feb 2008 07:42:28 -1100 Subject: sata_mv: remove iounmap in mv_platform_remove and use devm_iomap this will fix crash bug when doing rmmod to the driver, this is because the port_stop function get called later and it could access the device's registers.
