[PATCH v2] ARM: cns3xxx: pci: avoid potential stack overflow

Hi,

Arnd Bergmann [off-list ref] writes:

With those two changes in place, we no longer need the fake
pci_sys_data/pci_bus structures for faking config space writes,
and the stack usage goes down as well.

 arch/arm/mach-cns3xxx/pcie.c | 71 +++++++++++++++++++++++++++++----------------------------------------

I'm ATM unable to test this change, but will do that at some point.
Meanwhile, I guess there is nothing I can say against this patch.
Thanks.
