Maybe you can send the entire patchset to linux-mtd next time, I can 
only see patch 5 from the maillist. After confirming from other 
website(https://www.spinics.net/lists/kernel/msg4727274.html) I see you 
instroduced the implementation of kobject_del_and_put().

I have no objections if other modules can accept the kobject_del_and_put().
