From 43d80439c5f619446e174abdbdaff4fc0e539546 Mon Sep 17 00:00:00 2001 From: Benjamin Herrenschmidt Date: Fri, 26 Jan 2007 19:07:54 -0800 Subject: [POWERPC] ps3: system bus minor mmio fix Fix two minor bugs in the PS3 system bus mmio region code. First, on error or when freeing a region, retain the bus_addr and len fields to allow subsequent calls to create the region. Second, correct the region address argument to the lv1_unmap_device_mmio_region() call. Fixes modprobe/rmmod of some drivers.
