[PATCH] powerpc/chrp: Fix detection of Python PCI host bridge on IBM CHRPs
From: Benjamin Herrenschmidt <benh@kernel.crashing.org>

The detection of the IBM "Python" PCI host bridge on IBM CHRP machines such as old RS6000 was broken when we changed of_device_is_compatible() from strncasecmp to strcasecmp (dropped the "n" variant) due to the way IBM encodes the chip version. We fix that by instead doing a match on the model property like we do for others bridges in that file. It should be good enough for those machines. If yours is still broken, let me know.
