From 32867fcc0ef9e56939d5200ad983801bbfd581ad Mon Sep 17 00:00:00 2001 From: Fabio Estevam Date: Thu, 31 Mar 2016 12:05:17 -0300 Subject: [PATCH] fec: Do not access unexisting register in Coldfire Commit 55cd48c821de ("net: fec: stop the "rcv is not +last, " error messages") introduces a write to a register that does not exist in Coldfire. Move the FEC_FTRL register access inside the FEC_QUIRK_HAS_RACC 'if' block, so that we guarantee it will not be used on Coldfire CPUs.
