Subject: [PATCH] erofs: make kobj_type structures constant
Date: Thu, 09 Feb 2023 03:21:13 +0000	[thread overview]
Message-ID: <20230209-kobj_type-erofs-v1-1-078c945e2c4b@weissschuh.net> (raw)

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.
