From 6c0244091e8aa98e7977bdddeab2bb864cff9d91 Mon Sep 17 00:00:00 2001 From: Betty Dall Date: Sat, 30 Apr 2016 10:03:38 -0600 Subject: [PATCH] ACPI / device_sysfs: Change _SUN and _STA show functions error return to EIO The error return from a sysfs show function is passed up through the call chain and visible as the return from the read system call. The show functions for the _STA and _SUN object currently return -ENODEV. This patch changes the return to -EIO. ENODEV makes less sense since the "device' exists or there wouldn't be a sysfs file.
