[PATCH] net: sfc: falcon: convert to i2c_new_dummy_device

[Wolfram Sang]

Move from i2c_new_dummy() to i2c_new_dummy_device(). So, we now get an
ERRPTR which we use in error handling.

Only build tested. Part of a tree-wide move to deprecate
i2c_new_dummy().

Solarflare folks, please review/test.

Thank you.

Subject & description are incomplete, you're also changing i2c_new_device()
 to i2c_new_client_device().

Falcon isn't likely to get tested by us, I think we only have about three
 of them left in the building, two of which are in display cabinets ;-)
We end-of-lifed this hardware a couple of years ago, maybe it should be
 downgraded from 'supported' to 'odd fixes'.  Or even moved to staging,
 like that qlogic driver recently was.

Right, this was an anomaly with this patch to have both code paths
returning an ERRPTR. The big conversion for i2c_new_device will come
later in a seperate series.
