Subject: x86/intel_rdt: Get rid of anon union
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=a83827d04f081b1a73845553c7f60ab9cfd13767;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

x86/intel_rdt: Get rid of anon union

gcc-4.4.3 fails to statically initialize members of a anon union.
See: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=10676

The storage saving is not really worth it and aside of that it will catch
usage of the cache member for bandwidth and vice versa easier.

Fixes: 05b93417ce5b ("x86/intel_rdt/mba: Add primary support for Memory Bandwidth Allocation (MBA)")
