Thanks for taking a look.

 From cover letter:

- removed static function names prefix from internal functions (external
   used function, such as devm/interrupts-handlers/probe, left with the
   prefix to allow stack trace visibility)

As you can see, part of the functions got their prefix removed, e.g. 
prepare_msg, handle_ce, handle_ue.

I did take your advise for leaving prefix for having visibility for 
functions being used outside. hence, some were left with the prefix.

Let me know what you think.
