[PATCH] xfs: make kobj_type structures constant
From: Thomas Weißschuh
Date: Wed Feb 08 2023 - 22:17:02 EST
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.
