Devices IDs are unlikely to be reused by mutiple subsystems, so
probably we don't need
to add them here?
Hi Jiaxun,
I think it is better to define the device IDs in pci_ids.h,
otherwise it seems a little disorganized.
Please read the comment at the start of this file.
New entries should be added only if they're shared by multiple drivers.
That's the rule.
And probably you can split these two patches into a new series
as they're likely to be accepted.
OK, that makes sense.
Let me split the two patches 1/6 and 2/6 into a new series,
the first patch only adds the Loongson vendor ID to pci_ids.h.
Thanks,
Tiezhu Yang
Thanks.
Thanks,
