[PATCH 2/3] Input: adp5589-keys - wrap device probing into chip info struct
From: Alexandru Ardelean <hidden>

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.
