Subject: [thermal-next PATCH 2/2] thermal: qcom: tsens: simplify debugfs init function
Date: Mon, 19 Apr 2021 03:29:30 +0200 [thread overview]
Message-ID: <20210419012930.7727-2-ansuelsmth@gmail.com> (raw)
In-Reply-To: <20210419012930.7727-1-ansuelsmth@gmail.com>
Simplify debugfs init function.
- Drop useless variables
- Add check for existing dev directory.
- Fix wrong version in dbg_version_show (with version 0.0.0, 0.1.0 was
incorrectly reported)
