Subject: [PATCH v1] PM / devfreq: tegra30: Add error message for devm_devfreq_add_device()
Date: Thu, 30 Jun 2022 10:57:51 +0300 [thread overview]
Message-ID: <20220630075751.1360786-1-dmitry.osipenko@collabora.com> (raw)
It's difficult to notice that driver failed to probe by looking at KMSG
when devm_devfreq_add_device() fails. Add explicit error message for this
case.
