Subject[PATCH v2] staging: unisys: Remove "struct dentry *eth_debugfs_dir"
Date
There is no need for "struct dentry *eth_debugfs_dir" which is used for
debug / sysfs directories. Therefore, remove this "struct dentry" and
everything related (i.e., creation and removal).

As a side effect of this change, the code has no more need of the
"cleanup_register_netdev" label, which can also be removed.

v1 - v2: Add a couple of "Suggested-by" tags which were forgotten.
Thanks to Dan Carpenter and Greg Kroah-Hartman.
