Subject: amd64_edac: Cleanup NBCTL code
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=c9f4f26eae096c39547139666e8af607c2447f94;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

amd64_edac: Cleanup NBCTL code

Remove family names from macro names, drop single bit defines and
comment their meaning instead.

No functional change.
