From 776cdc11b3b0fc21e34600e22abe1c8209d2f3f0 Mon Sep 17 00:00:00 2001 From: Guenter Roeck Date: Wed, 28 Mar 2012 09:03:26 -0700 Subject: hwmon: (acpi_power_meter) Fix compiler warning seen in some configurations 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().
