Improve debugfs_start_creating() to warn if it was used before debugfs initialization. It silently returned ERR_PTR(-ENOENT) before, but it is hard to find the cause of failure especially if it was called by debugfs_create_dir(), because the document of the function says: > NOTE: it's expected that most callers should _ignore_ the errors returned > by this function. Other debugfs functions handle the fact that the "dentry" > passed to them could be an error and they don't crash in that case. > Drivers should generally work fine even if debugfs fails to init anyway.
