pci_probe_reset_function - check whether the device can be safely reset : PCI device to reset

Some devices allow an individual function to be reset without affecting other functions in the same device. The PCI device must be responsive to PCI config space in order to use this function.

Returns 0 if the device function can be reset or negative if the device doesn't support resetting a single function.

Definition at line 1508 of file pci.c.

void platform_pci_wakeup_init ( struct pci_dev dev)

platform_pci_wakeup_init - init platform wakeup if present : PCI device

Some devices don't have PCI PM caps but can still generate wakeup events through platform methods (like ACPI events). If supports platform wakeup events, set the device flag to indicate as much. This may be redundant if the device also supports PCI PM caps, but double initialization should be safe in that case.
