Subject: [PATCH v2 1/2] thermal: qcom: tsens: remove data indirection in the debugfs
Date: Sun, 26 Sep 2021 16:42:36 +0300	[thread overview]
Message-ID: <20210926134237.23863-1-dmitry.baryshkov@linaro.org> (raw)

There is no reason to pass platform device to debugfs just to get the
tsens_priv from it. Not to mention that for TSENS_V0 the platform device
(gcc) might have other device data. Pass the tsens_priv data to debugfs
callbacks directly.
