powerpc: Add const qual to local_read() parameter
A patch in net-next triggered a compile error on powerpc: include/linux/u64_stats_sync.h: In function 'u64_stats_read': include/asm-generic/local64.h:30:37: warning: passing argument 1 of 'local_read' discards 'const' qualifier from pointer target type This seems reasonable to relax powerpc local_read() requirements. Fixes: 316580b69d0a ("u64_stats: provide u64_stats_t type") Signed-off-by: Eric Dumazet <edumazet@google.com> Reported-by: kbuild test robot <lkp@intel.com> Acked-by: Michael Ellerman <mpe@ellerman.id.au> Tested-by: Stephen Rothwell <sfr@canb.auug.org.au> # build only Signed-off-by: Jakub Kicinski <jakub.kicinski@netronome.com>
