  regulator: core: Export helpers used by regulator couplers (2026-09-25 18:44:46 +0100)

----------------------------------------------------------------
regulator: core: Export helpers used by regulator couplers

regulator_check_voltage(), regulator_check_consumers(),
regulator_do_balance_voltage() and regulator_coupler_register() are
already declared in include/linux/regulator/coupler.h for regulator
coupler implementations to use, but none of them is exported. That
limits couplers to being built into the kernel.

Export them so that coupler drivers can be built as loadable modules.
