In the Linux kernel, the following vulnerability has been resolved:

spi: rockchip-sfc: Fix DMA-API usage

Use DMA-API dma_map_single() call for getting the DMA address of the
transfer buffer instead of hacking with virt_to_phys().

This fixes the following DMA-API debug warning:
------------[ cut here ]------------
DMA-API: rockchip-sfc fe300000.spi: device driver tries to sync DMA memory it has not allocated [device address=0x000000000cf70000] [size=288 bytes]
