5561955b11
Previously the internal programmer used its own code to initialize pcilib. This patch extracts the common code from the internal programmer and pcidev_init() into pcidev_init_common(). This fixes the non-existent PCI cleanup of the internal programmer and adds an additional safety by checking for an already existing PCI context. We got a nice shutdown function registration infrastructure, but did not use it very wisely. Instead we added shutdown functions to a myriad of programmers unnecessarily. In this patch we get rid of those that do only call pci_cleanup(pacc) by adding a shutdown function the pcidev.c itself that gets registered by pcidev_init(). Corresponding to flashrom svn r1642.
