[lm-sensors] [PATCH 1/3] hwmon: (acpi_power_meter) Fix unintentional integer overflow

[Guenter Roeck]

Expression with two integer variables is calculated as integer before it is
converted to u64. This may result in an integer overflow. Fix by declaring
the constant as ULL.

This patch addresses Coverity #200596: Unintentional integer overflow.
