global: Avoid warnings about unused variables - #9998
Conversation
Not sure this is right way, now there's another: sof/src/ipc/ipc4/helper.c:945:31: error: unused variable 'sof_uuid' [-Werror,-Wunused-variable] The sof_uuid is used with tr_warn(). The stub_build step is possibly disabling all traces. Edit - and a few more added. Seems these are relevant, so I'm not closing this. |

Pull Request Overview
This pull request addresses warnings about unused variables across multiple modules, contributing to cleaner builds on stub-check configurations.
- In src/platform/posix/ipc.c, unused variables were removed or relocated under conditional compilation.
- In src/ipc/ipc4/helper.c, an unused argument is explicitly cast to void.
- In the smart amp modules and IGO NR modules, unused variables were removed or cast to void to prevent warnings.

- The removal of the 'cc' variable assignment is acceptable if this variable is not used in subsequent processing; please verify that its removal does not affect any later functionality.
struct sof_ipc_comp *cc = global_ipc->comp_data;

Please consider __maybe_unused

| (void)sof_uuid; /* Avoid possible warning of unused */ |

@singalsu You should be able to use "__maybe_unused" attribute for these cases. See examples in Zephyr and SOF, often used for variables that are checked in asserts and log statements that may be omitted in production builds.

Ah that was it, I had vague memory of something like that but I could not find example. I'll change, stay tuned.

Updated now, it looks like the stubs build passed with green check mark with __maybe_unused.
