The drivers/acpi/battery.c init function starts with:
static int __init acpi_battery_init(void)
{
if (acpi_disabled)
return;
[ ... ]
This could cause problems because, if ACPI is disabled, the driver init function would return 0 (success) without being initialised.
The following compiler warning is shown when compiling Precise kernel:
/home/henrix/src/precise/ubuntu-precise/drivers/acpi/battery.c: In function 'acpi_battery_init':
/home/henrix/src/precise/ubuntu-precise/drivers/acpi/battery.c:1172:3: warning: 'return' with no value, in function returning non-void [-Wreturn-type]
