If an interrupt arrives after\ndevm_request_irq() and before init_completion(), the handler calls\ncomplete() on an uninitialized completion, causing a kernel panic.\n\nThe probe path, in lpc32xx_adc_probe():\n\n    iodev = devm_iio_device_alloc(&pdev->dev, sizeof(*st)); /* st kzalloc-zeroed */\n    ...\n    retval = devm_request_irq(&pdev->dev, irq, lpc32xx_adc_isr, 0,\n                              LPC32XXAD_NAME, st);           /* register handler */\n    ...\n    init_completion(&st->completion);                       /* initialize completion */\n\nlpc32xx_adc_isr() calls complete():\n\n    complete(&st->completion);\n\nIf the device raises an interrupt before init_completion() runs,\ncomplete() acquires the uninitialized wait.lock and walks the zeroed\ntask_list in swake_up_locked(). The zeroed task_list makes list_empty()\nreturn false, so swake_up_locked() dereferences a NULL list entry,\ntriggering a KASAN wild-memory-access.\"\n\nFix the chance of a spurious IRQ causing an uninitialized pointer\ndereference by moving init_completion() above devm_request_irq()."
