+Subject: [PATCH] regulator: consumer: Add missing stubs to
+ regulator/consumer.h
+
+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().

+
+Backport from mainline to fix build failure when CONFIG_REGULATOR=n which
+is default in linux-yocto.
+5.10.114 in mainline stable tree does not handle this case.
