Warn more loudly when an i2c-adapter is registered without a parent.
There should be almost no driver left in this case, and it's about
time to fix these.

could be done but remove the battery and reboot.
So could you give a suggestion? Is there any useful way to protect from
entering this abnormal UNIT-BUSY i2c status or recover from that?
I don't know anything about PXA platforms, there's nothing I can do for
you, sorry.

These methods were useful in the legacy binding model but no longer in
the new (standard) binding model. There are no users left so we can
drop them.

We converted all the legacy i2c drivers so we can finally get rid of
the legacy binding model. Hooray!

Now that i2c_attach_client is no longer exported, it doesn't need to
be a separate function. Merge it into its only user, i2c_new_device.

Legacy i2c drivers are gone, all drivers are new-style now, so there
is no point to check.

We don't need to give adapters a parent if they don't have one. The
driver core will put them in the virtual device directory and all will
be fine.

Much better than my first attempt. Not sure what will happen if we ever
turn i2c-adapters into bus
gracefully. I'll Cc you when I post it (in a
minute), please give it a try if you can.
