CVE-2026-89993

dmaengine: dw-edma: Initialize IRQ data before requesting IRQs

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

dmaengine: dw-edma: Initialize IRQ data before requesting IRQs

dw_edma_irq_request() passes struct dw_edma_irq to request_irq() before
dw_edma_channel_setup() fills the back pointer. A shared interrupt can
therefore enter the handler with dw_irq->dw still NULL, leading to a
NULL pointer dereference.

Set the back pointer before installing each handler.
