[ Upstream commit b8806e0c939f168237593af0056c309bf31022b0 ] Fix following warning (with CONFIG_DMA_API_DEBUG) which happens with a transfer without a data buffer. DMA-API: i3c mipi-i3c-hci.0: device driver tries to free DMA memory it has not allocated [device address=0x0000000000000000] [size=0 bytes] For those transfers the hci_dma_queue_xfer() doesn't create a mapping and the DMA address pointer xfer->data_dma is not set.
