Subject: [PATCH] irq: make kobj_type structures constant
Date: Fri, 17 Feb 2023 03:16:25 +0000	[thread overview]
Message-ID: <20230217-kobj_type-irq-v1-1-fedfacaf8cdb@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.
