This is a small follow-up series to a larger cleanup series already
sent:

("treewide: simplify getting the adapter of an I2C client")

These drivers use a bit different but still unnecessarily complex way to
determine the adapter of a client. Thanks to Peter Rosin for pointing
them out. They have been fixed manually, no need for a coccinelle script
here. Build tested, too. From the previous cover-letter:

The I2C core populates the parent pointer of a client as:
	client->dev.parent = &client->adapter->dev;

Now take into consideration that
	to_i2c_adapter(&adapter->dev);

is a complicated way of saying 'adapter', then we can even formally
prove that the complicated expression can be simplified by using
client->adapter.

A branch can be found here:

git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux.git i2c/no_to_adapter

Please apply the patches to the individual subsystem trees. There are no
dependencies.

Thanks and kind regards,

   Wolfram
