-/**
- * pcie_port_acpi_setup - Request the BIOS to release control of PCIe services.
- * @port: PCIe Port service for a root port or event collector.
- * @srv_mask: Bit mask of services that can be enabled for @port.
- *
- * Invoked when @port is identified as a PCIe port device.  To avoid conflicts
- * with the BIOS PCIe port native services support requires the BIOS to yield
- * control of these services to the kernel.  The mask of services that the BIOS
- * allows to be enabled for @port is written to @srv_mask.
- *
- * NOTE: It turns out that we cannot do that for individual port services
- * separately, because that would make some systems work incorrectly.
