Subject: [PATCH] mtd: rawnand: cadence: fix incorrect device in
dma_unmap_single
commit f37d135b42cb484bdecee93f56b9f483214ede78 upstream.
dma_map_single is using physical/bus device (DMA) but dma_unmap_single
is using framework device(NAND controller), which is incorrect.
Fixed dma_unmap_single to use correct physical/bus device.
Fixes: ec4ba01e894d ("mtd: rawnand: Add new Cadence NAND driver to MTD subsystem")
