After commit b8a1a4cd5a ("i2c: Provide a temporary .probe_new()
call-back type"), all drivers being converted to .probe_new() and then
03c835f498 ("i2c: Switch .probe() to not take an id parameter") convert
back to (the new) .probe() to be able to eventually drop .probe_new() from
struct i2c_driver.

The PinePhone keyboard case contains a battery managed by an integrated
power bank IC. The power bank IC communicates over I2C, and the keyboard
MCU firmware provides an interface to read and write its registers.
Let's use this interface to implement a SMBus adapter, so we can reuse
the driver for the power bank IC.
