 * __pci_reset_function - reset a PCI device function

 * @dev: 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.

 *

 * The device function is presumed to be unused when this function is called.

 * Resetting the device will make the contents of PCI configuration space

 * random, so any caller of this must be prepared to reinitialise the

 * device including MSI, bus mastering, BARs, decoding IO and memory spaces,

 * etc.

 *

 * Returns 0 if the device function was successfully reset or negative if the

 * device doesn't support resetting a single function.
