Message-id: <1447921070-6045-7-git-send-email-cw00.choi@samsung.com> Date: Thu, 19 Nov 2015 17:17:50 +0900 From: Chanwoo Choi <cw00.choi@...sung.com> To: myungjoo.ham@...sung.com, kyungmin.park@...sung.com Cc: linux-kernel@...r.kernel.org, linux-pm@...r.kernel.org, Chanwoo Choi <cw00.choi@...sung.com> Subject: [PATCH 6/6] PM / devfreq: Set the min_freq and max_freq of devfreq device After probing the devfreq device driver, the value of both min_freq and max_freq are zero(0). So, this patch initializes the 'min_freq' and 'max_freq' field of devfreq device by using the freq_table array.
