If anyone has any objections, please let me know. ------------------ From: Marek Szyprowski [ Upstream commit cb3fcb8d118b874178251d1f02613f60d25e4ddc ] When transfer was stopped in STATE_DATA_BUSY state, there was no call to dma_ops->cleanup function, so the DMA mapped buffer was never properly unmapped. Fix this by calling dw_mci_stop_dma() function also in that state to ensure proper cleanup call when DMA transfer was used.
