Subject: Make topology fallback macros reference their arguments.
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=271cad6d7e91ff8eea18976311692f99cd667ad3;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git

Make topology fallback macros reference their arguments.

This avoids warnings with unreferenced variables in the !NUMA case.
