From ff22b4806dd79ba06c78255b67e73c10e34d47cc Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Fri, 15 Apr 2016 17:47:20 +0300 Subject: hp_accel: Silence an uninitialized variable warning If acpi_evaluate_integer() fails then "lret" isn't initialized. I've tweaked the error handling to avoid this issue.
