The call\nto stdev_release() then happens during close or exit, at a point way past\nswitchtec_pci_remove(). Otherwise the last ref would vanish with the\ntrailing put_device(), just before return.\n\nAt that later point in time, the devm cleanup has already removed the\nstdev-\u003emmio_mrpc mapping. Also, the stdev-\u003epdev reference was not a counted\none. Therefore, in DMA mode, the iowrite32() in stdev_release() will cause\na fatal page fault, and the subsequent dma_free_coherent(), if reached,\nwould pass a stale \u0026stdev-\u003epdev-\u003edev pointer.\n\nFix by moving MRPC DMA shutdown into switchtec_pci_remove(), after\nstdev_kill(). Counting the stdev-\u003epdev ref is now optional, but may prevent\nfuture accidents.\n\nReproducible via the script at\nhttps://lore.kernel.org/r/20231113212150.96410-1-dns@arista.com"
