drivers/rapidio/devices/rio_mport_cdev.c: NUL terminate some strings
[ Upstream commit 156e0b1a8112b76e351684ac948c59757037ac36 ]
The dev_info.name[] array has space for RIO_MAX_DEVNAME_SZ + 1
characters. But the problem here is that we don't ensure that the user
put a NUL terminator on the end of the string. It could lead to an out
of bounds read.
