power: supply: sbs-battery: Don't needlessly set CAPACITY_MODE
According to the smart battery spec (1), the CAPACITY_MODE bit does not influence the value read from RelativeStateOfCharge(), so don't bother changing CAPACITY_MODE when doing such a read. (1) - Smart Battery Data Specification, Rev 1.1, Dec. 11, 1998 Signed-off-by: Shawn Nematbakhsh <shawnn@chromium.org> Reviewed-by: Guenter Roeck <groeck@chromium.org> Signed-off-by: Sebastian Reichel <sebastian.reichel@collabora.co.uk>
