Re: [PATCH] drm/tegra: hub: Do not enable orphaned window group

Though the unconditional enable/disable code is not a final solution, we don't want to run into a NULL pointer situation when window group doesn't link to its DC parent if the DC is disabled in Device Tree.

So this patch simply adds a check to make sure that window group has a valid parent before running into tegra_windowgroup_enable/disable.
