power_supply: bq25890: make chip_id int
Smatch static checker correctly detected an impossible condition because
chip_id was declared as u8, instead of int:
drivers/power/bq25890_charger.c:843 bq25890_probe()
warn: impossible condition '(bq->chip_id < 0) => (0-255 < 0)'
Also, while at it, fix the return value too.
