4.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Bjorn Helgaas <bhelg...@google.com>
[ Upstream commit fae846e2b7124d4b076ef17791c73addf3b26350 ]
The device ID alone does not uniquely identify a device. Test both the
vendor and device ID to make sure we don't mistakenly think some other
vendor's 0xB410 device is a Digium HFC4S. Also, instead of the bare hex
ID, use the same constant (PCI_DEVICE_ID_DIGIUM_HFC4S) used in the device
ID table.
No functional change intended.
