	Currently, sun4i_dma_free_contract iterates over lists and frees memory as it goes through them, causing reads to recently freed memory to be performed. Fix this by using the safe version of the iterator, so freed memory is not referenced at all.

2015-08-20	dmaengine: sun4i: Add support for the DMA engine on sun[457]i SoCs	Emilio López
	This patch adds support for the DMA engine present on Allwinner A10, A13, A10S and A20 SoCs. This engine has two kinds of channels: normal and dedicated. The main difference is in the mode of operation; while a single normal channel may be operating at any given time, dedicated channels may operate simultaneously provided there is no overlap of source or destination. Hardware documentation can be found on A10 User Manual (section 12), A13 User Manual (section 14) and A20 User Manual (section 1.12) Signed-off-by: Emilio López <emilio@elopez.com.ar> Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Maxime Ripard <maxime.ripard@free-electrons.com> Signed-off-by: Vinod Koul <vinod.koul@intel.com>
