If anyone has any objections, please let me know. ------------------ From: Ben Dooks [ Upstream commit 89aba9c39bdda8a973a6ffed7c9e93321edcfc16 ] When writing the lli->ctl_hi, this is an __le32 type so the value being orred should be convered to __le32 by cpu_to_le32. Fixes 1deb96c0fa58a ("dmaegine: dw-axi-dmac: Support device_prep_dma_cyclic()") -- Note, the call to axi_chan_irq_clear() is passing lli->status_lo through which is also an __le32 but it does not seem to be set anywhere. Is this also a bug?
