Puede ocurrir una eliminación en caliente del dispositivo PCI mientras stdev->cdev se mantiene abierto. La llamada a stdev_release() ocurre durante el cierre o la salida, en un punto mucho más allá de switchtec_pci_remove(). De lo contrario, la última referencia desaparecería con el put_device() final, justo antes del retorno. En ese momento posterior, la limpieza devm ya eliminó la asignación stdev->mmio_mrpc. Además, la referencia stdev->pdev no se contaba. Por lo tanto, en modo DMA, iowrite32() en stdev_release() causará un error de página fatal, y el dma_free_coherent() posterior, si se alcanza, pasaría un puntero &stdev->pdev->dev obsoleto. Para solucionarlo, mueva el apagado de MRPC DMA a switchtec_pci_remove(), después de stdev_kill(). Contar stdev->pdev ref ahora es opcional, pero puede evitar accidentes futuros.
