[PATCH] staging: unisys: Remove "struct dentry *eth_debugfs_dir"

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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, test, 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.
