In cops_probe1(), there is a write to dev->base_addr after requesting an interrupt line and registering the interrupt handler cops_interrupt(). The handler might be called in parallel to handle an interrupt. cops_interrupt() tries to read dev->base_addr leading to a potential data race. So write to dev->base_addr before calling request_irq(). Found by Linux Driver Verification project (linuxtesting.org).
