Note, this is not always safe to do. If "drivers", "pci" or "hotplug" ever
become a macro, the path will also be updated, and this will fail to build.

diff --git a/include/uapi/linux/pci.h b/include/uapi/linux/pci.h

The safer way to do this is to have:

In drivers/pci/hotplug/Makefile:

CFLAGS_pciehp_ctrl.o := -I$(src)

And replace the TRACE_INCLUDE_PATH to:

#define TRACE_INCLUDE_PATH .

Got it. Will fix it in next version.

Thanks.
