[PATCH] power_supply: max8998: Use devm_power_supply_register

Show all headers | View raw

Use managed resource function devm_power_supply_register
instead of power_supply_register. To be compatible with the
change, replace various gotos by direct returns and remove
unneeded label err.

Also, remove max8998_battery_remove as it is now redundant.
