 - RT:  Removed the p_msg field from the thread_t structure saving a
        msg_t-sized field from the structure. Messages now use a new field
        into the p_u union. Now synchronous messages are even faster.
+- HAL: Fixed unused variable in STM32 SPIv2 driver (bug #705)(backported
+       to 16.1.3).
