I noticed this in KMSG:
tegra-mc 7000f000.memory-controller: overwriting group->as for swgroup: g2 debugfs: File 'g2' in directory 'mappings' already present! tegra-mc 7000f000.memory-controller: overwriting group->as for swgroup: g2 debugfs: File 'g2' in directory 'mappings' already present
Doesn't look okay, please fix.
