thermal: stm32: Fix stm_thermal_read_factory_settings
Adding brackets allows to multiply the register value, masked by TS1_RAMP_COEFF_MASK, by an ADJUST value properly and not to multiply ADJUST by register value and then mask the whole. Fixes: 1d693155 ("thermal: add stm32 thermal driver") Reviewed-by: Daniel Lezcano <daniel.lezcano@linaro.org> Signed-off-by: David Hernandez Sanchez <david.hernandezsanchez@st.com> Signed-off-by: Eduardo Valentin <edubezval@gmail.com>
