Subject: drm/radeon: properly track the crtc not_enabled case evergreen_mc_stop()
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=804cc4a0ad3a896ca295f771a28c6eb36ced7903;p=openwrt%2Fstaging%2Fblogic.git

drm/radeon: properly track the crtc not_enabled case evergreen_mc_stop()

The save struct is not initialized previously so explicitly
mark the crtcs as not used when they are not in use.
