It looks like you turned a set of spaces into a tab for the writew()
line. Please don't make such whitespace changes in the same patch as
other changes.

Yes, lots of things to learn before you get your first patch accepted...

This seems like an error message. So maybe

     pr_err("NONONONOO!!!!\n");

These ATM drivers don't appear to be netdev drivers. There does not
appear to be a struct device available, so you have to fall back to
pr_err(), pr_info() etc.
