Function parameters cannot shadow statics

Cross-post from #318, because I don't really know where I should ask this question.

I'm working on a project that is based on esp-idf-template and when I'm trying to include esp-idf-hal in my Cargo.toml compilation fails with the following error:

error[E0530]: function parameters cannot shadow statics

error: could not compile `esp-idf-hal` due to 3 previous errors

I'm compiling on MacOS with ESP IDF v5.0.

Any idea what is wrong?

After a bit more investigation, I noticed that this error occurs when adding an extra component esp-camera. My Cargo.toml contains:

package.metadata.esp-idf-sys]
extra_components = [
    { component_dirs = [ "vendor" ], bindings_header = "src/bindings.h" }
]

And I have a bindings.h that contains #include "esp_camera.h". When removing the extra_components my project compiles without errors.

And I've just pushed my code to https://github.com/wouterdebie/esp32-cam-rs

Closing in favor of esp-rs/esp-idf-hal#182 and esp-rs/esp-idf-hal#183
