The related code are not necessary because,
- Device status and general registers can be obtained by ethtool.
- Coredump can be done via devlink health reporter.
- Structure related to the hardware (struct ql_adapter) can be obtained
by crash or drgn.

I would suggest to add the drgn script from the cover letter to
Documentation/networking/device_drivers/qlogic/

Thank you for this suggestion! I planned to send a pull request to
https://github.com/osandov/drgn. This is a better idea.

I would also suggest to submit a separate patch now which fixes the
build breakage reported in <20200629053004.GA6165@f3> while you work on
removing that code.

I'll send a single patch to fix that issue before preparing for v1
of this work.

This leaves a stray newline at the end of the file and also does not
apply over latest staging.

I will fix it in v1. Thank you for reviewing this patch!
