Subject: [PATCH v2 4/4] hwmon: (w83795) use find_closest_desc() in pwm_freq_to_reg()
Date: Tue, 10 Mar 2015 18:27:22 +0100	[thread overview]
Message-ID: <1426008442-26236-5-git-send-email-bgolaszewski@baylibre.com> (raw)
In-Reply-To: <1426008442-26236-1-git-send-email-bgolaszewski@baylibre.com>

Replace the loop iterating over pwm_freq_cksel0 with a call to
find_closest_desc().
