This is a small follow-up series to a larger cleanup series already sent:
http://patchwork.ozlabs.org/project/linux-i2c/list/?series=112605 ("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
