4.2-stable review patch. If anyone has any objections, please let me know.
------------------ From: Robert Jarzmik <[email protected]> commit aebf5a67db8dbacbc624b9c652b81f5460b15eff upstream. Since the commit to have an allocated list of virtual descriptors was reverted, the pxa_dma driver is broken, as it assumes the descriptor is placed on the allocated list upon allocation. Fix the issue in pxa_dma by making an allocated virtual descriptor a singleton.
