Thank you for the input...

Let's say I set it to "mstar,msg2638", is it better to rename the driver file and functions too ?
According to downstream source file naming, msg2638 is the model I have and test this driver with.


There's a possibility this driver works as-is or with minor mods for msg2633 too,
and a more remote one for msg21xx and msg22xx...
