Subject: mm: cma: make kobj_type structure constant
Date: Mon, 20 Feb 2023 23:23:31 +0000
Since commit ee6d3dd4ed48 ("driver core: make kobj_type constant.") the
driver core allows the usage of const struct kobj_type.
Take advantage of this to constify the structure definition to prevent
modification at runtime.
