[PATCH 1/6] bus: fsl-mc: drop useless cleanup

From: laurentiu . tudor
Date: Tue Feb 08 2022 - 09:59:46 EST


From: Laurentiu Tudor <laurentiu.tudor@xxxxxxx>

This cleanup is actually a no-op because the resources are freed when
the device objects are removed from the allocator at driver remove
time.
