[PATCH] PCI Hotplug: Fix OSHP calls in shpchp and pciehp drivers
Here is a patch to fix a problem in OSHP calls in shpchp and pciehp
drivers that was detected in 2.6.11-rc3. In this kernel, calls to
acpi_evaluate_object() to evaluate OSHP returned AE_BUFFER_OVERFLOW
with the existing code. Earlier kernels didn't return this error
code. The correct fix should be making return_buffer pointer NULL
for no value is returned from this method.
