From: Wu Bo <wubo.o...@gmail.com> m_can_handle_state_change() is called with the new_state as an argument.
In the switch statements for CAN_STATE_ERROR_ACTIVE, the comment and the following code indicate that a CAN_STATE_ERROR_WARNING is handled. This patch fixes this problem by changing the case to CAN_STATE_ERROR_WARNING.
