Thanks a lot for splitting up the patch. I don't mind redoing the
second part of the patch, but I'm not sure if it's actually needed to
prevent memory leaks. This piece of code serves as an example:

+error_unreg2:
+ sysfs_remove_bin_file(&f_dev->kobj, &fw_priv->attr_data);
error_unreg:
device_unregister(f_dev);

Perhaps device_unregister() call above already removes the kobj which
makes the added sysfs_remove_bin_file() unnecessary?

Cheers,
