Greg Kroah-Hartman 04f3cda40e staging: pi433: fix memory leak with using debugfs_lookup()
[ Upstream commit 2f36e789e5 ]

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.  This requires saving off the root directory dentry to make
creation of individual device subdirectories easier.
