Problem with HAL RTC libraries

[JFels]

In the function:

HAL_RTCEx_DisableBypassShadow()

There is a cast to uint8_t in the line that resets the bit

hrtc->Instance->CR &= ((uint8_t)~RTC_CR_BYPSHAD);

This causes the upper 24 bits of this configuration register to be cleared to 0s when called. Everywhere else I looked in the HAL RTC code when resetting bits in this register it is using a (uint32_t) cast.

This was found in the library:

STM32Cube_FW_L4_V1.7.0

as well as

STM32Cube_FW_F4_V1.21.0
