From a055f9ecb5b4d0cb8b33ba664363a2ed7804a6c7 Mon Sep 17 00:00:00 2001 From: "Darren Hart (VMware)" Date: Wed, 19 Apr 2017 18:11:33 -0700 Subject: [PATCH] platform/x86: hp-wmi: Do not shadow errors in sysfs show functions The new hp_wmi_read_int function returns a negative value in case of error, pass this on directly rather than always replacing it with -EINVAL.
