pci_set_drvdata() is called only after registering the net_device, therefore we could run into a NPE if one of the functions using driver_data is called before it's set. Fix this by calling pci_set_drvdata() before registering the net_device. This fix is a candidate for stable. As far as I can see the bug has been there in kernel version 3.2 already, therefore I can't provide a reference which commit is fixed by it. The fix may need small adjustments per kernel version because due to other changes the label which is jumped to if register_netdev() fails has changed over time.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
