security: testing the wrong variable in create_by_name()
There is a typo here. We should be testing "*dentry" instead of "dentry". If "*dentry" is an ERR_PTR, it gets dereferenced in either mkdir() or create() which would cause an OOPs. Signed-off-by: Dan Carpenter <error27@gmail.com> Signed-off-by: James Morris <jmorris@namei.org>
