It forced the baud to 9600 on the first call to pl2303_set_termios() Based on the tty changes in the 2.6.27 kernel, the termios passed to the *_set_termios functions is always populated the first time. This means there is no need to privately initialize the settings the first time, and doing so will not allow the use of the kernel parameter "console=ttyUSB0,115200" as an example.

Rather than changing the typedef, we put the "const" in all the various places where its required, allowing the __initconst exception for nfsroot which was the cause of the previous trouble. This was posted for review some time ago and I believe its been in -mm since then.
