X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=4a3a1dc02fc3245aeeaa3742791e71fa2497b4a0;p=linux.git drm/amd/display: Initialize num_pkrs on VANGOGH. As far a I can tell uses a variant of DCN3xx which uses num_pkrs. If we do not initialize the variable we will set the register field to ilog2(0) = -1, though the mask will reduce that to 7. Pretty sure 7 is not the value we want here.
