Subject[60/90] sunsu: Fix detection of SU ports which are RSC console or control.
2.6.31-stable review patch.  If anyone has any objections, please let us know.

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


From: David S. Miller <davem@davemloft.net>

[ Upstream commit 8301d386afc55c877bafe2c6c7dc75a96ddd2838 ]

These device nodes are named "rsc-console" and "rsc-control" rather
than 'serial', but the device_type property is 'serial' so we'll
tip off of that for detection.
