[ 107/123] PCI: Work around Stratus ftServer broken PCIe hierarchy (fix DMI check)

[Greg Kroah-Hartman]

3.7-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Myron Stowe <myron.stowe@xxxxxxxxxx>

commit 1278998f8ff6d66044ed00b581bbf14aacaba215 upstream.

Commit 284f5f9 was intended to disable the "only_one_child()" optimization
on Stratus ftServer systems, but its DMI check is wrong.  It looks for
DMI_SYS_VENDOR that contains "ftServer", when it should look for
DMI_SYS_VENDOR containing "Stratus" and DMI_PRODUCT_NAME containing
"ftServer".

Tested on Stratus ftServer 6400.
