PCI/MSI: Don't apply affinity if there aren't enough vectors left
Bart reported a problem wіth an out of bounds access in the low-level IRQ affinity code, which we root caused to the qla2xxx driver assigning all its MSI-X vectors to the pre and post vectors, and not having any left for the actually spread IRQs. Fix this issue by not asking for affinity assignment when there are no vectors to assign left.

untime PM framework triggered by recent changes in i915. Specifics: - Add an intel_pstate driver quirk to work around a firmware setting that leads to frequency scaling issues on desktop Intel Kaby Lake processors in some configurations if the hardware-managed P-states (HWP) feature is in use (Srinivas Pandruvada) - Fix up the recently added brcmstb-avs cpufreq driver: fix a bug related to system suspend and change the sysfs interface to match the user space expectations (Markus Mayer) - Modify the runtime PM framework to avoid false-positive warnings from the might_sleep_if() assertions in it (Rafael Wysocki)" * tag 'pm-4.10-rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: PM / runtime: Avoid false-positive warnings from might_sleep_if() cpufreq: intel_pstate: Disable energy efficiency optimization cpufreq: brcmstb-avs-cpufreq: properly retrieve P-state upon suspend cpufreq: brcmstb-avs-cpufreq: extend sysfs entry brcm_avs_pmap
