[PATCH] power: supply: bq256xx: Remove init ichg/vbat with max value

From: Hermes Zhang
Date: Tue Nov 29 2022 - 04:01:31 EST


Init the ichg and vbat reg with max value is not good. First the chip
already has a default value for ichg and vbat (small value). Init these
two reg with max value will result an unsafe case (e.g. battery is over
charging in a hot environment) if no user space change them later.
