I have no objections from my side, though consider the following:
- I would like to be in sync with Darren on this
- make oldconfig will be broken after your change for existing users
- the usual pattern in kernel that we don't rename drivers; I guess
here we are on the safe side b/c this driver is used standalone
Taking above into attention, and assuming it will go via some other tree,
