If anyone has any objections, please let me know. ------------------ From: Chen Ni commit 0410e1a4c545c769c59c6eda897ad5d574d0c865 upstream. Fix wrong variable used for error checking after dma_alloc_coherent() call. The function checks cdns_ctrl->dma_cdma_desc instead of cdns_ctrl->cdma_desc, which could lead to incorrect error handling.
