[PATCH 1/2] ACPI: battery: Fix CONFIG_ACPI_SYSFS_POWER=n

[Alan Jenkins <alan-jenkins@tuffmail.co.uk>]

Disabling CONFIG_ACPI_SYSFS_POWER changes the behaviour of
acpi_battery_update().  It will call acpi_battery_get_info()
even if the battery is not present.  I haven't noticed this
causing any problem, but it does look like a bad idea.
