[STM32L412] CubeMX generated LL code for ADC TEMP channel

[ml512]

Hi,

I'm using CubeMX 6.11.0 (STM32L4 package version 1.18.0) to generate code for the STM32L412 with LL drivers.

My configuration enables the VREFINT and TEMP channels for ADC1.

The generated function MX_ADC1_Init() contains the line

LL_ADC_SetCommonPathInternalCh(__LL_ADC_COMMON_INSTANCE(ADC1), LL_ADC_CHANNEL_VREFINT|LL_ADC_CHANNEL_TEMPSENSOR);

which should actually be

LL_ADC_SetCommonPathInternalCh(__LL_ADC_COMMON_INSTANCE(ADC1), LL_ADC_PATH_INTERNAL_VREFINT | LL_ADC_PATH_INTERNAL_TEMPSENSOR);

This prevents correct temperature channel measurements.
