[v8,0/3] i2c: improve i2c_new_{device|dummy}

Message

Hiya,

so, here is a new version as a result of the discussion.

Changes since V7:

* dropped the 'errptr' suffix and renamed the functions to
  'i2c_new_client_device' and 'i2c_new_dummy_device'

* add EXPORT_SYMBOL_GPL to these new functions

I decided to convert the users of i2c_new_device and i2c_new_dummy to
the new functions after these functions are available. So, we can get
rid of the old functions somewhen. To speed this up, I'd like to send
them this merge window to Linus. Yeah, this is short notice, but I
simply couldn't work earlier on this because of my illness. So, if you
can support me with immediate (but still thorough!) reviews, that would
be much appreciated. If we can get it upstream this cycle, then I can
already start fixing the users.

Patch 3 is only for demonstration purposes, of course. I will send it to
the MFD list once the dependencies are upstream.

Tested on a Renesas Lager board (R-Car Gen2).

Looking forward to comments,

   Wolfram
