From 19e5c3e745c798a3d9a969c362470fb6b14d6a45 Mon Sep 17 00:00:00 2001 From: Florian Fainelli Date: Wed, 30 Mar 2011 20:10:48 +0000 Subject: [PATCH] [package] flashrom: use msr path compatible w/ hotplug2 The issue wasn't that flashrom-0.9.3 was broken, but that the incompatible device path put the box into a funky state that couldn't be reverted.
