From 9fb81ce63671f9743517f628dac935269f2581a9 Mon Sep 17 00:00:00 2001 From: Alan Stern Date: Fri, 14 Apr 2006 16:46:28 -0400 Subject: [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.
