No, drop it.

Besides the redundant blank line this call to i2c_of_match_device() is not good.
of_data is a misleading name. What about ACPI?
What you are looking for is:
data = device_get_match_data(&client->dev);

Don't use I2C id field, switch to i2c ->probe_new() if it's not done yet.

Please, use pointers as in of_device_id table.
