If ioremap of PCIe ctrl memory failed we can still get to it through PCI config space, therefore we allow ioremap() to fail. When if fails, however, we must leave all the IOMEM pointers as NULL. Currently we would calculate csr and em pointers, adding offsets to the potential NULL value and therefore making the NULL-checks throughout the code ineffective.

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.
