HAL_I2C_Master_Abort_IT mode HAL_I2C_MODE_MEM not supported

[pocpos]

Set-up

• STM32L496 MCU with I2C device which required I2C-memory transfer (HAL_I2C_Mem_Write_IT /HAL_I2C_Mem_Read_IT)
• STM32CubeIDE Version: 1.16.0
• STM32CubeL4 MCU Firmware Package 1.18.0

Describe the bug In case of a error condition, the firmware should call HAL_I2C_Master_Abort_IT(), but this doesn't abort the transfer, because the the internal mode HAL_I2C_MODE_MEM is not support by this function.

Hint For "STM32CubeL5 MCU Firmware Package" this bug is already fixed. Please use the "L5" fix for "L4" too!

Function -> STM32L4 - incomplete

HAL_StatusTypeDef HAL_I2C_Master_Abort_IT(I2C_HandleTypeDef *hi2c, uint16_t DevAddress)
{
  if (hi2c->Mode == HAL_I2C_MODE_MASTER)
  {
    /* Process Locked */
    __HAL_LOCK(hi2c);

...

Function -> STM32L5 - working version

HAL_StatusTypeDef HAL_I2C_Master_Abort_IT(I2C_HandleTypeDef *hi2c, uint16_t DevAddress)
{
  HAL_I2C_ModeTypeDef tmp_mode = hi2c->Mode;

  if ((tmp_mode == HAL_I2C_MODE_MASTER) || (tmp_mode == HAL_I2C_MODE_MEM) )
  {
    /* Process Locked */
    __HAL_LOCK(hi2c);
