CubeMX generates extra MultiMode config for slave channel that causes init fail

[devinw]

I'm setting up Dual Regular Simultaneous mode on my STM32H533RE and I cane across a problem. When the code is gerated, both MX_ADC1_Init() and MX_ADC2_Init() end up with this:

/** Configure the ADC multi-mode

*/

// multimode.Mode = ADC_DUALMODE_REGSIMULT;

// multimode.DMAAccessMode = ADC_DMAACCESSMODE_12_10_BITS;

// multimode.TwoSamplingDelay = ADC_TWOSAMPLINGDELAY_1CYCLE;

// if (HAL_ADCEx_MultiModeConfigChannel(&hadc2, &multimode) != HAL_OK)

// {

// Error_Handler();

// }

WhereHAL_ADCEx_MultiModeConfiChannel expects MASTER as the first argument.

So when I start up, ADC1 inits fine, but ADC2 fails because it tries to run that above function

with hadc2 as the master, even though it is a slave, and has a HAL config error.

If I comment out the above block on MX_ADC2_Init, all seems to work well.

Is this a bug? Or can I do something different in CubeMX to make this not happen?
