Hello Greg,

The idea for the helper was inspired by the comment Dan made to Bjorn
about Bjorn's change, as per:

  https://lore.kernel.org/driverdev-devel/20191016135002.GA24678@kadam/

It looked like a good idea to try to reduce the following:

  dev->driver && dev->driver->pm && dev->driver->pm->prepare

Into something more succinct.  Albeit, given the feedback from yourself
and Rafael, I gather that this helper is not really a good addition.

Thank you everyone and sorry for the commotion!

Krzysztof
