Subject: drm/tegra: Run hub cleanup on ->remove()
Git-commit: d66dfcf80d0f55f95b9ea4a45ca41cc7115e9789
Patch-mainline: v5.5-rc1
References: bsc#1152489
The call to tegra_display_hub_cleanup() that takes care of disabling the
window groups is missing from the driver's ->remove() callback. Call it
to make sure the runtime PM reference counts for the display controllers
are balanced.
