Because the interrupt may occur immediately after devm_request_irq(), the handler may execute before init_completion(). This may result in calling complete() on an uninitialized completion, causing undefined behavior. This has been observed with KASAN. The driver attempts to use an internal synchronization mechanism before it has been properly set up. If an interrupt occurs at a precise moment, the system may try to operate on this uninitialized mechanism, leading to unpredictable system behavior. This could result in system instability or a…
