efi: x86: make kobj_type structure constant

t-8ch · ardbiesheuvel · commit 42a8af0fa433 · 2023-05-10T19:00:40.000+02:00
Since commit ee6d3dd ("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. Signed-off-by: Thomas Weißschuh <linux@weissschuh.net> Signed-off-by: Ard Biesheuvel <ardb@kernel.org>
