This auto build testing is a great service, but is there any way to
tweak the info above to make it easier to reproduce the problem?

I tried to checkout the source that caused these errors, but failed.
This is probably because I'm not a git expert, but maybe others are in
the same boat.  For example, I tried:

  $ git remote add kbuild https://github.com/0day-ci/linux/commits/Vaibhav-Gupta/drivers-ide-use-generic-power-management/20200625-013242
  $ git fetch kbuild
  fatal: repository 'https://github.com/0day-ci/linux/commits/Vaibhav-Gupta/drivers-ide-use-generic-power-management/20200625-013242/' not found

I also visited the github URL in a browser, and I'm sure there must be
information there that would let me fetch the source, but I don't know
enough about github to find it.

The report doesn't include a SHA1, so even if I *did* manage to fetch
the sources, I wouldn't be able to validate they were the *correct*
ones.
