Subject: mfd: ab8500: Use power_supply_*() API for accessing function attrs
X-Git-Tag: v4.9.8~4492^2~25
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=091e73a23a81efd2a01523178e9086ed346384ac;p=platform%2Fkernel%2Flinux-rpi3.git

mfd: ab8500: Use power_supply_*() API for accessing function attrs

Replace direct calls to power supply function attributes with wrappers.
Wrappers provide safe access in case of unregistering the power
supply (e.g. by removing the driver). Replace:
 - get_property -> power_supply_get_property
