Subject: mm/damon/sysfs: make kobj_type structures constant
Date: Tue, 07 Feb 2023 19:21:15 +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 definitions to prevent
modification at runtime.
