This leads to a stacktrace as acpi_battery_get_property() returns 0 for a
case where it does not set val->intval. These value is used as an array
index in
drivers/power/power_supply_sysfs.c::power_supply_show_property(). I had a
situation where the value was 4096 which caused a problem as the array
only has 5 entries.

Rolf, thanks for remainding.

Huh? This one is unrelated to the problem I reported two weeks ago...

Eike
You are second to send the same patch, first one I already acked.
But it seems that Len did not pick it up yet.
Look for "ACPI: Always return valid 'status' from acpi_battery_get_property()"
if interested...

Regards,
Alex.
