In some configurations, BUG() does not result in an endless loop but returns
to the caller. This results in the following compiler warning:
drivers/hwmon/acpi_power_meter.c: In function 'show_str':
drivers/hwmon/acpi_power_meter.c:380: warning: 'val' may be used uninitialized in this function
Fix the warning by setting val to an empty string after BUG().
