Subject: [PATCH] drm/mcde: Fix an error handling path in 'mcde_probe()'
[ Upstream commit 15c665bb4637310bc8ce5f357b6a6e5a8aafc7c1 ]
If we don't find any matching components, we should go through the error
handling path, in order to free some resources.
Fixes: ca5be902a87d ("drm/mcde: Fix uninitialized variable")
