Greg Kroah-Hartman cf042964c2 tty: pcn_uart: fix memory leak with using debugfs_lookup() 
[ Upstream commit 04a189c720aa2b6091442113ce9b9bc93552dff8 ]

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.
