Subject: [PATCH 2/3] Input: adp5589-keys - wrap device probing into chip info struct
This change wraps the devices supported by the adp5589 driver into a chip
info struct. With this, a device table can be created, and the probed
device can be selected based on the enum value provided by the i2c driver
data.
