From e3a411a3dfc1d633504aa63efab32b7e00318454 Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Thu, 28 Dec 2006 21:01:32 -0800 Subject: [SPARC64]: Fix of_iounmap() region release. We need to pass in the resource otherwise we cannot release the region properly. We must know whether it is an I/O or MEM resource. Spotted by Eric Brower. Signed-off-by: David S.
