commit d1541dc9 upstream.

In fixup_ti816x_class(), we assigned "class = PCI_CLASS_MULTIMEDIA_VIDEO".
But PCI_CLASS_MULTIMEDIA_VIDEO is only the two-byte base class/sub-class
and needs to be shifted to make space for the low-order interface byte.

Shift PCI_CLASS_MULTIMEDIA_VIDEO to set the correct class code.

Fixes: 63c44080 ("PCI: Add quirk for setting valid class for TI816X Endpoint")
