* ds2760_battery.c: fix division by zeroDaniel Mack2009-03-121-4/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The 'battery remaining capacity' calculation in drivers/power/ds2760_battery.c lacks a parameter check to a division operation which causes the kernel to oops on my board. [ 21.233750] Division by zero in kernel.

| | | | | | | | | | | | | | | Since 43cc71eed1250755986da4c0f9898f9a635cb3bf ("platform: prefix MODALIAS with "platform:"), the platform modalias is prefixed with "platform:". Add MODULE_ALIAS() to the hotpluggable "power" drivers drivers, to re-enable auto loading.
