From b5254867f941efa7a621362a98f1349f59473c61 Mon Sep 17 00:00:00 2001 From: Mark Einon Date: Fri, 19 Oct 2012 23:08:16 +0100 Subject: [PATCH] staging: et131x: Remove USE_FBR0 define and #ifdefs USE_FBR0 has always been defined, even in the original driver code. Remove the define and #ifdef code to leave the code in the same state.
