[PATCH] powerpc: add const qual to local_read() parameter

From: Eric Dumazet
Date: Fri Nov 08 2019 - 09:14:01 EST


A patch in net-next triggered a compile error on powerpc.

This seems reasonable to relax powerpc local_read() requirements.

Fixes: 316580b69d0a ("u64_stats: provide u64_stats_t type")
