Subject: [PATCH] powerpc/numa: remove unreachable topology workqueue code
References: bsc#1181674 ltc#189159
Patch-mainline: v5.9-rc1
Git-commit: 6325cb4a4ea8f4af8515b923650dd8f709694b44
Since vphn_enabled is always 0, we can remove the call to
topology_schedule_update() and remove the code which becomes
unreachable as a result.
