Hi Hao,
For this patch, can I keep your reviewed-by?
I just added ExceptionList in MdeModulePkg\MdeModulePkg.ci.yaml, to avoid CI failure.
Thanks
Zhiguang

主题: [edk2-devel] [Patch V5 2/9] MdeModulePkg: Add new structure for the PCI Root Bridge Info Hob
V5:
Add ExceptionList in MdeModulePkg\MdeModulePkg.ci.yaml, to avoid open CI
issue, because UID and HID are terms which are already used in current
source code.
