    kernel: Add missing devm_regulator_get_exclusive()
    
    This backports a patch from Linux 5.10.116 to fix a compile problem
    introduced in 5.10.114.
    
    drivers/usb/phy/phy-generic.c could not find
    devm_regulator_get_exclusive().
    
    Fixes: 8592df67f40b ("kernel: bump 5.10 to 5.10.114")

+Subject: [PATCH] regulator: consumer: Add missing stubs to
+ regulator/consumer.h
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+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().
