drivers: base: dd: fix memory leak with using debugfs_lookup()
[ Upstream commit 36c893d3 ] 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. Cc: "Rafael J.
