[PATCH v2] bus: mhi: host: pci_generic: Add macro for some VIDs

[PATCH v2] bus: mhi: host: pci_generic: Add macro for some VIDs

[Slark Xiao]

To make code neat and for convenience purpose, use macro for
some VIDs. These macros are supposed to be added to pci_ids.h.
But until the macros are used in multiple places, it is not
recommended. So adding it locally for now.

No, they are not supposed to be added there at all.

And they are not a "macro", it is a "#define".

Again, these are not macros

Hi Greg,
Thanks for your comment.
In my opinion, MACRO almost same as a '#define'.  May I know how do 
you call such definition?

And could you give your comments in previous patch, not the 'final' one?
In another pci_ids patch, you break it in v3 and break it here again in v2.
Honestly,  it's positive for whole project. But it's negative  for contributor 
and maintainer. 

Finally, it's welcome to point out the error.

As I said, this is just a define, not a macro at all.

I do not understand, what previous patrch?  What "final" one?  What is
the "latest" patch?

> In another pci_ids patch, you break it in v3 and break it here again in v2.

I broke what?

I am totally confused here and do not understand what you are referring
to, sorry.

You could have  voiced out such comment in V1, V2 before the 'final'.

That's 2 different versions, with a total of 3.

We all review patches when we can.  There is no rule that people can not
comment on newer patches, or older ones.

In fact, it would be wonderful if you could take some time and review
patches from others.  It would help your understanding of the code and
how the kernel development process works.

Agree with this.  But you know, 5 attempt   just for a little update  were rejected
It's so frustrating. Anyway, I re-submit another v3 patch for this change.
Please give your comment if you are free.

Thanks
