patch

I tried the drm-fixes-3.13 branch but it crashes for me in hwmon_attributes_visible. If I revert commit ec39f64bba3421c2060fcbd1aeb6eec81fe0a42d (drm/radeon/dpm: Convert
to use devm_hwmon_register_with_groups) the crash disappears.

The attached patch fixes the issue for me. I only had a problem with the hwmon_attributes_visible function, but looking at the code it seems to me that the same fix is needed in radeon_hwmon_show_temp_thresh as well.
