No I didn't test the code. And I don't have the required hardware. But I would like to know what are widely used test methods in linux kernel dev to test a driver when you don't have the relevant hardware vs when you have one for and finally test the code. At first it seemed a trivial change to me because that else block would only execute if the if-elseif block didnt execute, which made me come to the decision that the else block was unnecessary.
