Subject: sensors-detect: Avoid probing EDID addresses on graphics cards
Patch-mainline: yes (r6040)
References: bnc#838619 lm-sensors#2386
Avoid probing EDID addresses (0x50-0x57) on graphics card adapters.
We had one report that it caused trouble:
http://lists.lm-sensors.org/pipermail/lm-sensors/2012-April/035847.html
Even though it's not yet clear what happened, let's play it safe.
This fixes ticket #2386.
