Depends on the result.  The bottom line is that you run your patched
kernel on the real hardware or equivalent (VM or emulation) for the
device you touched.

Hopefully, if you stop asking another new question for each word.

Run your patched kernel and the driver code on the real machine with
the corresponding device.  Show the device is running.  That's the
very first step.  Then follow the more detailed tests, but it depends
on the subsystem.
