From: Bean Huo <beanhuo@xxxxxxxxxx> In 'include/ufs/ufshcd.h' file, 'enum dma_data_direction' will be used, which is defined in linux/dma-direction.h, however, this header file is not included in ufshcd.h, thus causing the following compilation warning: "warning: ‘enum dma_data_direction’ declared inside parameter list will not be visible outside of this definition or declaration" Fix this warning by including 'linux/dma-direction.h'.
