[PATCH 00/12] i2c: convert subsystem to use i2c_new_client_device()

[Wolfram Sang]

This patch series converts the I2C subsystem to use the new API. Drivers
have been build tested. There is one user left in the SMBus part of the
core which will need a seperate series because all users of this
function need to be checked/converted, too.

Except for documentation patches, the conversion has been done with a
coccinelle script and further simplification have been applied when
proofreading the patches.

A branch is here:

git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux.git renesas/i2c/new_client_device

Looking forward to comments...

Move away from the deprecated API and return the shiny new ERRPTR where
useful.
