Subject: drm/amd/pp: Fix bug voltage can't be OD separately on VI
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=8d80fada066bec682f1b7e9015b8412e3460c1b3;p=openwrt%2Fstaging%2Fblogic.git

drm/amd/pp: Fix bug voltage can't be OD separately on VI

Make sure to update the MCLK and SCLK flags when setting the VDDC
flags due to dependencies.
