Steps to reproduce the problem:
Our tool DeepTect detect a potential null pointer exception in /base/android/java/src/org/chromium/base/library_loader/Linker.java

There is a potential null pointer exception:

if (sSingleton == null) {
  setImplementationForTesting(type);
  sSingleton.setTestRunnerClassNameForTesting(testRunnerClassName);
  return;
}

If "sSingleton" is equal to null, there is a null point exception when it calls the method "setTestRunnerClassNameForTesting" inside the if statement.

What is the expected behavior?
