I'm on a quest to clean up compiler warnings in drivers/pci. I'd like to be able to treat warnings as errors, at least for the 0day build robot. ---

Previously we checked the device_attach() return value only when CONFIG_BUG=y. That caused this warning in builds where CONFIG_BUG is not set: dri

We've already looked up srv->port a few lines earlier, and there's no need to do it again. Remove the redundant lookup. Signed-off-by: Bjorn Helgaas

Previously we had this: if (wakeup) ret = enable_irq_wake(...); if (!wakeup || ret) ... "ret" is only evaluated when "wakeup" is true, a

We've had some non-arch-specific stuff (pci_has_flag() and associated definitions like PCI_PROBE_ONLY) in asm/pci-bridge.h. This leads to warnings li

The PCI flag management constants and functions were previously declared in include/asm-generic/pci-bridge.h. But they are not specific to bridges, a

In POWER8, OCC(On-Chip-Controller) can throttle the frequency of the CPU when the chip crosses its thermal and power limits. Currently, powernv-cpufre

This will free the dynamically allocated memory of 'chips' on module exit. Signed-off-by: Shilpasri G Bhat <shilpa.bhat@linux.vnet.ibm.com> Reviewed-

In the kworker_thread powernv_cpufreq_work_fn(), we can end up sending an IPI to a cpu going offline. This is a rare corner case which is fixed using

cpu_to_chip_id() does a DT walk through to find out the chip id by taking a contended device tree lock. This adds an unnecessary overhead in a hot pat
