Message-Id: <1461957681-6163-3-git-send-email-betty.dall@hpe.com> Date: Fri, 29 Apr 2016 13:21:20 -0600 From: Betty Dall <betty.dall@....com> To: rjw@...ysocki.net, lenb@...nel.org, linux-acpi@...r.kernel.org Cc: linux-kernel@...r.kernel.org, Betty Dall <betty.dall@....com> Subject: [PATCH v2 2/3] 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.
