Subject: [PATCH v2] hwmon: pmbus: pxe1610: don't bail out when not all pages are active
Date: Fri, 16 Apr 2021 13:29:04 +0300 [thread overview]
Message-ID: <20210416102926.13614-1-fercerpav@gmail.com> (raw)
In-Reply-To: <3612b78a-8e43-289b-ff0f-6c995995eeb0@roeck-us.net>
Certain VRs might be configured to use only the first output channel and
so the mode for the second will be 0. Handle this gracefully.
Fixes: b9fa0a3acfd8 ("hwmon: (pmbus/core) Add support for vid mode detection per page bases")
