regulator: fix voltage check in regulator_is_supported_voltage()
regulator_is_supported_voltage() should return true only if the voltage of fixed/constant regulator is between min_uV and max_uV. Signed-off-by: Marek Szyprowski <m.szyprowski@samsung.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Cc: stable@vger.kernel.org
