1. An object should be declared in block scope if its identifier is only referenced within one function(MISRA C-2012 Rule8.9) 2. Casting from signed int to unsigned int is not allowed(MISRA C-2012 Rule 10.4) ## Summary 1.Fix MISRA C-2012 Rule 10.4 - avoid implicit signed to unsigned cast: Issue: Coverity detected an implicit conversion from signed integer to unsigned integer in the irqchain_attach() function of [irq_chain.c]. 2.Fix MISRA C-2012 Rule 8.9 - declare objects in block scope Coverity detected that the static array g_irqchainpool[] is declared at file scope but is only referenced by the irqchain_initialize() function. According to MISRA Rule 8.9, objects that are only referenced within a single function should be declared in block scope. ## Impact Positive Impact: Type Safety: Explicit unsigned literal eliminates implicit type conversions Encapsulation: Private variables properly scoped; namespace pollution reduced MISRA Compliance: Both Rule 10.4 and Rule 8.9 violations eliminated Code Clarity: Type intent explicit; variable scope immediately obvious Maintainability: Limited visibility reduces accidental modification risk Coverity Issues: Both static analysis warnings completely eliminated Zero-Risk Areas: Functionality: Program behavior completely unchanged Performance: No runtime overhead; type suffix has no performance cost Compatibility: Full backward compatibility; API/ABI unchanged Initialization: Static storage duration preserved; initialization semantics identical Memory Layout: Data structures unchanged; no memory layout impact ## Testing *This section should provide a detailed description of what you did to verify your changes work and do not break existing code.* *Please provide information about your host machine, the board(s) you tested your changes on, and how you tested. Logs should be included.* *For example, when changing something in the core OS functions, you may want to run the OSTest application to verify that there are no regressions. Changes to ADC code may warrant running the `adc` example. Adding a new uORB driver may require that you run `uorb_listener` to verify correct operation.* *Pure documentation changes can just be tested with `make html` (see docs) and verification of the correct format in your browser.* **_PRs without testing information will not be accepted. We will request test logs._** -- This is an automated message from the Apache Git Service. To respond to the message, please log on to GitHub and use the URL above to go to the specific comment.
