Subject: [thermal-next PATCH v2 1/2] thermal: qcom: tsens: init debugfs only with successful probe
Date: Thu, 29 Apr 2021 03:05:17 +0200	[thread overview]
Message-ID: <20210429010518.13319-2-ansuelsmth@gmail.com> (raw)
In-Reply-To: <20210429010518.13319-1-ansuelsmth@gmail.com>

calibrate and tsens_register can fail or PROBE_DEFER. This will cause a
double or a wrong init of the debugfs information. Init debugfs only
with successful probe fixing warning about directory already present.
