Update hfi1 to use PCI-IDs as an identification in debugfs, instead
of device name which can be changed after user executes device rename.

Nak for now. This isn't quite what we have in mind. Patch is on the way,
going through review and testing. Will post soon to for-next.
Awesome, can you shed the light and summarize why this patch isn't good
fit for you?
The patch is very similar, our version, which is part of a bigger
series, doesn't use local variable and changes the pr_warn() calls to
dd_dev_warn(). I can go ahead and post our version, or you could make a
v2 to fix the pr_warns, up to you. The local variable vs non isn't a big
concern here, meaning I'm fine either way.
