Code inspection: Meaningless [MustDisposeResource] annotation for an input parameter

This inspection reports [MustDisposeResource] on an input parameter such as a regular, in, or ref readonly parameter. That annotation is meaningless for an input parameter because the method is receiving an existing value instead of returning a resource that the caller must dispose.

Example

                using JetBrains.Annotations;
                void Use([MustDisposeResource] IDisposable resource)
                {
                    resource.Dispose();
                }
            

                void Use(IDisposable resource)
                {
                    resource.Dispose();
                }
            

Quick-fix

There is no dedicated quick-fix for this inspection. A typical correction is to remove the annotation from the input parameter.
