Subject: mm/damon/sysfs: make more kobj_type structures constant
Date: Fri, 24 Mar 2023 15:35:27 +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.
These structures were not constified in commit e56397e8c40d
("mm/damon/sysfs: make kobj_type structures constant") as they didn't
exist when that patch was written.
