Ugh. Please, implement it as a function.

And maybe place it somewhere into linux/power_supply.h?

Something like this maybe?

static inline bool power_supply_is_amp_prop(enum power_supply_property psp)
{
	switch (psp) {
	case POWER_SUPPLY_PROP_CHARGE_NOW:
	case POWER_SUPPLY_PROP_CHARGE_FULL:
	case POWER_SUPPLY_PROP_CHARGE_FULL_DESIGN:
	<...>
		return 1;
	}
	return 0;
}

Thanks!
