Generated functions in module usbd_cdc_if have wrong return values

Hi !

This issue relates to:

<LINK NO LONGER ACTIVE>

Although the module functions should return a value of the enumeration USBD_StatusTypeDef

/* Following USB Device status */
typedef enum {
 USBD_OK = 0,
 USBD_BUSY,
 USBD_FAIL,
}USBD_StatusTypeDef;�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?

the return value of the generated functions is int8_t

static int8_t CDC_Init_FS (void);
static int8_t CDC_DeInit_FS (void);
static int8_t CDC_Control_FS (uint8_t cmd, uint8_t* pbuf, uint16_t length);
static int8_t CDC_Receive_FS (uint8_t* pbuf, uint32_t *Len);�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?

for example:

/**
 * @brief CDC_Init_FS
 * Initializes the CDC media low layer over the FS USB IP
 * @param None
 * @retval Result of the operation: USBD_OK if all operations are OK else USBD_FAIL
 */
static int8_t CDC_Init_FS(void)
{ 
�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?

should be changed to

/**
 * @brief CDC_Init_FS
 * Initializes the CDC media low layer over the FS USB IP
 * @param None
 * @retval Result of the operation: USBD_OK if all operations are OK else USBD_FAIL
 */
static USBD_StatusTypeDef CDC_Init_FS(void)�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?
