Module probing with the parameter documented yielded this in kernel log:

        gpio_mockup: unknown parameter 'gpio_named_lines' ignored

The parameter documented did not match the parameter actually
implemented with commit 8a68ea00a62e ("gpio: mockup: implement naming
the lines") long before introducing the documentation.

Fixes: commit 2fd1abe99e5f ("Documentation: gpio: add documentation for gpio-mockup")

         This parameter doesn't take any arguments. It lets the driver know that
         GPIO lines exposed by it should be named.
