| From | Yinghai Lu <> | Subject | [PATCH v11 38/60] PCI: Check if resource is allocated before trying to assign one | Date | Thu, 7 Apr 2016 17:15:51 -0700 |
| |
In following alt_size support, we will call pci_assign_resource() several times on one resource list, and some resources could have been assigned already.
Skip allocated resource in the list, as pci_assign_resource() only can handle not assigned resource.
