Directory name does not match with Namespace declaration

After installing laravel-pdf by composer and follow config steps, I've got a fatal exception for PdfServiceProvider class.

All classes are configured for 'Haska\Pdf' namespace, but the directory was called 'PDF' (uppercased), causing this error.
