From: Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx> [ Upstream commit ad0e4e2fab928477f74d742e6e77d79245d3d3e7 ] When calling debugfs_lookup() the result must have dput() called on it, otherwise the memory will leak over time. To make things simpler, just call debugfs_lookup_and_remove() instead which handles all of the logic at once.
