Subject: [PATCH] PM / devfreq: Fix handling dev_pm_qos_remove_request result
Date: Thu, 12 Mar 2020 05:15:11 +0200 [thread overview]
Message-ID: <ea4c8b53f2a045116a5f70e24374ce62c85f0b81.1583982882.git.leonard.crestez@nxp.com> (raw)
The dev_pm_qos_remove_request function can return 1 if
"aggregated constraint value has changed" so only negative values should
be reported as errors.
Fixes: 27dbc542f651 ("PM / devfreq: Use PM QoS for sysfs min/max_freq")
Reported-by: Dan Carpenter <dan.carpenter@oracle.com>
