With GKI we find in certain situations the timing of the drivers loading is delayed as compared to a monolithic kernel. This introduces a race where during second stage init, the attributes inside /sys/bus/platform/drivers/drm_dsi_ctrl might not be set by the time the menu is painted on the screen. To address this, we wait for /sys/class/drm/card0 to instantiate.
