New Revision: 253654
URL: http://svnweb.freebsd.org/changeset/base/253654
Log:
Set the device description after we call uart_probe(). In uart_probe()
we call device-specific probe functions, which can (and typically will)
set the device description based on low-level device probe information.
In the end we never actually used the device description that we so
carefully maintained in the PCI match table. By setting the device
description after we call uart_probe(), we'll print the more user-
friendly description by default.
