There is no need for a comment, just this line is fine:

If you note, no other lines have comments.

If you want to say that this is a specific device, then use a #define with that device name and then use that define here, like the PCI_DEVICE_ID_TI_DRA72x was done.

[Xiaowei Bao] Hi Greg, OK, I can remove the comments in the next version patch.
