Subject	[patch 12/37] serial: Fix sparc driver name strings.

2.6.25-stable review patch.  If anyone has any objections, please let us
know.

[ Upstream commit: b53e5216e5f73330bffae93b42dceb94e361f4c0 ]

They were all "serial" so if multiple of these drivers registered,
we'd trigger sysfs directory creation errors:
