regulator: Fix regulator_get_error_flags() signature mismatch
The function signature of does not match regulator_get_error_flags() when CONFIG_REGULATOR is not defined vs. when it is not defined. This makes both declarations match to prevent compiler errors. Signed-off-by: David Lechner <david@lechnology.com> Signed-off-by: Mark Brown <broonie@kernel.org>
