影响性分析说明：
In the Linux kernel, the following vulnerability has been resolved:

mmc: mmci: stm32: fix DMA API overlapping mappings warning

DMA API debug brings to light leaking dma-mappings as dma_map_sg and
dma_unmap_sg are not correctly balanced.

If an error occurs in mmci_cmd_irq function, only mmci_dma_error
function is called and as this API is not managed on stm32 variant,
dma_unmap_sg is never called in this error path.
