Subject: [PATCH 1/2] ACPI: battery: Fix CONFIG_ACPI_SYSFS_POWER=n
Date: Fri, 11 Dec 2009 11:04:42 +0000 [thread overview]
Message-ID: <4B22274A.1000003@tuffmail.co.uk> (raw)
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.
