[PATCH 5.18 0065/1095] RISC-V: Declare cpu_ops_spinwait in <asm/cpu_ops.h>

From: Greg Kroah-Hartman
Date: Mon Aug 15 2022 - 16:16:55 EST


From: Ben Dooks <ben.dooks@xxxxxxxxxx>

commit da6d2128e56a50a0d497c8e41ca1d33d88bcc0aa upstream.

The cpu_ops_spinwait is used in a couple of places in arch/riscv
and is causing a sparse warning due to no declaration. Add this
to <asm/cpu_ops.h> with the others to fix the following:

arch/riscv/kernel/cpu_ops_spinwait.c:16:29: warning: symbol 'cpu_ops_spinwait' was not declared. Should it be static?
