the point here is to solve the problem of linking to an LGPL licensed library, to comply you can: a) release the code of the original LPGL licensed library b) release it with a patch of any modifications, ie the small change here c) nothing else. zero. No license changes. No other code of the app affected. No app code needs to be released. And you are compliant with the LGPL license and can get on with life. So this is not a big deal the way GPL code in the app would be which would require the app code to be re-licensed and released to comply, which is a huge deal and difficult to accomplish.
