[PATCH] USB: net2280: set driver data before it is used
This patch (as671) fixes a bug in the error pathway for the net2280 probe routine. A failure during probe will cause the driver to call pci_get_drvdata before the corresponding pci_set_drvdata has been set. The patch also does a kzalloc conversion.
