[ Upstream commit b5a1f8921d5040bb788492bf33a66758021e4be5 ]
There is a small race where the parent is NULL even though the kobj has
already been made visible in sysfs.
For instance the attribute_group is made visible in sysfs_create_files()
and the mdev_type_attr_show() does:
ret = attr->show(kobj, type->parent->dev, buf);
Which will crash on NULL parent. Move the parent setup to before the type
pointer leaves the stack frame.
Fixes:
