Greg Kroah-Hartman 68f22c80c1 debugfs: add debugfs_lookup_and_remove() ...

commit dec9b2f1e0 upstream.

There is a very common pattern of using
debugfs_remove(debufs_lookup(..)) which results in a dentry leak of the
dentry that was looked up.  Instead of having to open-code the correct
pattern of calling dput() on the dentry, create
debugfs_lookup_and_remove() to handle this pattern automatically and
properly without any memory leaks.
