Subject: [PATCH 5.10 02/10] regulator: consumer: Add missing stubs to regulator/consumer.h

From: Dmitry Osipenko <digetx@...il.com>

commit 51dfb6ca3728bd0a0a3c23776a12d2a15a1d2457 upstream.

Add missing stubs to regulator/consumer.h in order to fix COMPILE_TEST
of the kernel. In particular this should fix compile-testing of OPP core
because of a missing stub for regulator_sync_voltage().
