Greg Kroah-Hartman cf1c917bf1 kernel/irq/irqdomain.c: fix memory leak with using debugfs_lookup() 
commit d83d7ed260 upstream.

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.
