Manual inspection showed that negative= results from platform_get_irq() were being replaced with fixed error codes. = For drivers matched via OF, this can discard -EPROBE_DEFER and prevent the dr= iver core from retrying once the interrupt controller becomes available. I co= mpared these paths with platform_get_irq() semantics and neighboring drivers. This was not a production hit or a syzbot report, and it was not found by a s= tatic-analysis scan. LLM assistance was used in preparing the patches, as dis= closed by the Assisted-by tag. The controllers were unavailable for runtime t= esting, so the series was build-tested only. Thanks, Chaosheng
