# \[PATCH\] ocxl: Use pci\_dev\_id() to simplify the code - From: Zheng Zengkai \ - Date: 2023-08-11 21:01:52 - List: linuxppc-dev - Page: https://ratatoskr.run/linuxppc-dev/2023/08/9531721 - Thread: https://ratatoskr.run/linuxppc-dev/2023/08/9531721/t.md ```text PCI core API pci_dev_id() can be used to get the BDF number for a pci device. We don't need to compose it mannually. Use pci_dev_id() to simplify the code a little bit.
