Sebastian suggested that the correct fix implemented by this patch, instead of my attempt in commit ea4367c40c79 ("power: supply: core: move power_supply_attr_group into #ifdef block"), is to define power_supply_attr_groups in power_supply_sysfs.c and expose it in the power_supply.h header. For the case where CONFIG_SYSFS=n, define it as NULL.
