Summary
time/debug: Fix memory leak with using debugfs_lookup()
Details

In the Linux kernel, the following vulnerability has been resolved:

time/debug: Fix memory leak with using debugfs_lookup()

When calling debugfslookup() the result must have dput() called on it, otherwise the memory will leak over time. To make things simpler, just call debugfslookupandremove() instead which handles all of the logic at once.
