Joakim Zhang 4985e507e0 dma-mapping: clear dev->dma_mem to NULL after freeing it ... [ Upstream commit b07bc2347672cc8c7293c64499f1488278c5ca3d ] Reproduced with below sequence: dma_declare_coherent_memory()->dma_release_coherent_memory() ->dma_declare_coherent_memory()->"return -EBUSY" error It will return -EBUSY from the dma_assign_coherent_memory() in dma_declare_coherent_memory(), the reason is that dev->dma_mem pointer has not been set to NULL after it's freed.
