Subject: drm/amd/powerplay: correct data type to support under voltage
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=9a412063f0940d23a5ef393c2607ca9ae9f8f0b7;p=openwrt%2Fstaging%2Fblogic.git

drm/amd/powerplay: correct data type to support under voltage

For under voltage, negative value will be applied to voltage
offset. Update the data type to cover this case.
