regulator: s2mps11: Use local variable for number of regulators
Remove the s2mps11_info.rdev_num because it is not used outside of probe. Suggested-by: Andi Shyti <andi.shyti@samsung.com> Signed-off-by: Krzysztof Kozlowski <k.kozlowski@samsung.com> Reviewed-by: Andi Shyti <andi.shyti@samsung.com> Signed-off-by: Mark Brown <broonie@kernel.org>
