Subject: [PATCH v3 10/12] wireless: iwlwifi: use <linux/units.h> helpers
Date:   Wed, 11 Dec 2019 23:38:17 +0900
Message-Id: <1576075099-3441-11-git-send-email-akinobu.mita@gmail.com>
In-Reply-To: <1576075099-3441-1-git-send-email-akinobu.mita@gmail.com>
References: <1576075099-3441-1-git-send-email-akinobu.mita@gmail.com>
Sender: linux-wireless-owner@vger.kernel.org
Precedence: bulk

This switches the iwlwifi driver to use celsius_to_kelvin() and
kelvin_to_celsius() in <linux/units.h>.
