Series | mISDN: hfcpci: Test both vendor & device ID for Digium HFC4S | expand |
From: helgaas@kernel.org Date: Mon, 18 Mar 2019 08:51:06 -0500 > From: Bjorn Helgaas <bhelgaas@google.com> > > 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. > > Signed-off-by: Bjorn Helgaas <bhelgaas@google.com> Applied, thanks.
