Subject: [PATCH] platform: chrome: chromeos_laptop: drop checks of NULL-safe functions
Date:   Tue, 20 Aug 2019 17:34:49 +0200
Message-Id: <20190820153449.7866-1-wsa+renesas@sang-engineering.com>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

No need to check the argument of i2c_unregister_device() and
property_entries_free() because the functions do check it.
