Attempt to build head -r337273 powerpc64 kernel via xtoolchain-llvm variant (binutils based) failed for: error: passing 'int *' to parameter of type 'uint32_t *'

(I tried building without WERROR .)

The error report from the build was:

The code in question is:

static int drm_mode_object_get(struct drm_device *dev,
                               struct drm_mode_object *obj, uint32_t obj_type)
{
        int new_id = 0;
        int ret;
        
        ret = drm_gem_name_create(&dev->mode_config.crtc_names, obj, &new_id);
        if (ret)
                return ret;
                                
        obj->id = new_id;
        obj->type = obj_type;
        return 0;
}

It looks like the code has been this way for a long time
(including drm2/drm_gem_names.h ).
