Subject: x86/MCE/AMD: Make kobj_type structure constant
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=7214b32b6f4c6c1385a52f2e3a7107f28349f505;p=linux.git

x86/MCE/AMD: Make kobj_type structure constant

Since

  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.
