[v1] x86/MCE/AMD: Make kobj_type structure constant

[PATCH] x86/MCE/AMD: Make kobj_type structure constant

Posted by Thomas Weißschuh 2 years, 6 months ago

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.
