Greg Kroah-Hartman 37ea7b630a debugfs: debugfs_lookup() should return NULL if not found 
Lots of callers of debugfs_lookup() were just checking NULL to see if
the file/directory was found or not.  By changing this in ff9fb72bc0
("debugfs: return error values, not NULL") we caused some subsystems to
easily crash.

Fixes: ff9fb72bc0 ("debugfs: return error values, not NULL")
