From 49d23cfcec5d36a91e118d28148d353bf8f0bc03 Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Sun, 13 May 2007 22:01:18 -0700 Subject: [PATCH] [SPARC64]: Be more resiliant with PCI I/O space regs. If we miss on the ranges, just toss the translation up to the parent instead of failing. Signed-off-by: David S.
