[kernel 2.6] Patch for mxser.c driver

[Bernard Pidoux]

Hi,

mxser driver in kernel 2.6.16 can compile but it does not drive the 
serial multiport adapter from Moxa.

According to Moxa documentation for version 1.8, msmknod script, 
downloaded from their support site, creates ttyM0-7 and cum0-7 tty 
devices with major numbers 30 and 35 by defaults.

However, in mxser.c major device numbers are still 174 and 175.

Here is a patch to change major tty device numbers to proper default values.

BTW, driver source that can be downloaded from Moxa support site will 
not compile :
