From 82013d988fc03a1b908b2b0360a1e34f6152fda6 Mon Sep 17 00:00:00 2001 From: Stanislaw Gruszka Date: Sat, 8 Jan 2011 15:24:37 +0100 Subject: [PATCH] mtd: amd76xrom: fix oops at boot when resources are not available For some unknown reasons resources needed by amd76xrom driver can be unavailable. And instead of returning an error, the driver keeps going and crash the kernel. This patch fixes the problem by making the driver return -EBUSY if the resources are not available.
