The easy way is to use the intended pointer: client->adapter These drivers do: to_i2c_adapter(client->dev.parent); The I2C core populates the parent pointer 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. The conversion was done using a coccinelle script with some manual indentation fixes applied on top. To avoid a brown paper bag mistake, I double checked this on a Renesas Salvator-XS board (R-Car M3N) and verified both expression result in the same pointer. Other than that, the series is only build tested. 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.
