Subject: power_supply: charger-manager: Fix dereferencing of ERR_PTR
X-Git-Tag: v4.9.8~4492^2~7
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=ecf896b97de9757fd835034ad849680218babc93;p=platform%2Fkernel%2Flinux-rpi3.git

power_supply: charger-manager: Fix dereferencing of ERR_PTR

If power_supply_register() fails do not dereference returned ERR_PTR.
The pointer was dereferenced to print name of battery which registration
failed. Instead use the name from the power supply description passed to
the power_supply_register() function.
