debugfs_create_dir() returns ERR_PTR and never returns NULL.
As Russell suggested, this patch set removes the error checking for
debugfs_create_dir(). This is because the DebugFS kernel API is developed
in a way that the caller can safely ignore the errors that occur during
the creation of DebugFS nodes. The debugfs APIs have a IS_ERR() judge in
start_creating() which can handle it gracefully. So these checks are
unnecessary.
Changes in v2:
- Update the subject prefix from net to wireless-next as suggested.
- Remove the err check instead of using IS_ERR to replace NULL check.
- Update the commit message and title.
