If IRQ occurs between calling devm_request_threaded_irq() and initializing dwc3_imx->dwc3, then null pointer dereference occurs since dwc3_imx->dwc3 is used in dwc3_imx8mp_interrupt(). The patch puts registration of the interrupt handler after initializing of neccesery data. Found by Linux Driver Verification project (linuxtesting.org). Signed-off-by: Nadezda Lutovinova <redacted>
