power: supply: cpcap-battery: use device_get_match_data() to simplify code
In the function cpcap_battery_probe(), the driver only needs the data object, so use device_get_match_data() instead, to make the code cleaner. Signed-off-by: Tang Bin <tangbin@cmss.chinamobile.com> Signed-off-by: Sebastian Reichel <sebastian.reichel@collabora.com>
