In https://github.com/STMicroelectronics/STM32CubeL4/blob/c5e83f31696c3da4fb374224471afd08d9d457b3/Drivers/STM32L4xx_HAL_Driver/Inc/stm32l4xx_ll_adc.h#L346 the comment for VREFINT_CAL_VREF says
/* Analog voltage reference (Vref+) value with which temperature sensor has been calibrated in production (tolerance: +-10 mV) (unit: mV). */
but it probably refers to the voltage reference with which VREFINT has been calibrated in production.
See also the same comment for TEMPSENSOR_CAL_VREFANALOG a couple of lines below.

I guess it's a "bug" report, because it's located in a source code... 🙂

This is a bug in source which results in flawless binary.
And even more so, as probably in all STM32 both voltages for the factory calibs are identical, so even if you follow the wrong comment, the result will be correct.
A bug nonetheless... 🙂
