Bjorn Helgaas 075b7d363c Revert "PCI/portdrv: Do not setup up IRQs if there are no users" ... This reverts commit 0e8ae5a6ff. 0e8ae5a6ff ("PCI/portdrv: Do not setup up IRQs if there are no users") reduced usage of IRQs when we don't think we need them. But Joey, Sergiu, and David reported choppy GUI rendering, systems that became unresponsive every few seconds, incorrect values reported by cpufreq, and high IRQ 16 CPU usage. Joey bisected the issues to 0e8ae5a6ff, so revert it until we figure out a better solution.
