From 48d58459fe991e48bf7e6638a0ded0f8cbd2fa3b Mon Sep 17 00:00:00 2001 From: Grant Likely Date: Thu, 1 Nov 2007 08:22:35 -0600 Subject: [PATCH] Fix region size check in mpc5200 FEC driver Driver shouldn't complain if the register range is larger than what it expects. This works around failures with some device trees.
