Hi, Vinod,
This patch is applied cleanly on the next branch in the dmaengine repo.
The next branch already includes a few new DSA/IAA device IDs in IDXD
driver.
Please check the patches and the reasons why the new IDs should be added:

Use IAA going forward?
Will fix it in v2.

What is using this devid beyond the driver that needs pci_ids.h addition?
No other usage beyond the driver. Will move it inside the driver.
