Subject: [PATCH 0/3] treewide: simplify getting the adapter of an I2C client, part2
Date: Mon, 10 Jun 2019 11:51:53 +0200 [thread overview]
Message-ID: <20190610095157.11814-1-wsa+renesas@sang-engineering.com> (raw)
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
