Subject: [PATCH 2/4] PM / devfreq: Export devfreq_get_freq_ragne symbol within devfreq
Date: Thu, 17 Jun 2021 15:05:44 +0900 [thread overview]
Message-ID: <20210617060546.26933-3-cw00.choi@samsung.com> (raw)
In-Reply-To: <20210617060546.26933-1-cw00.choi@samsung.com>
In order to get frequency range within devfreq governors,
export devfreq_get_freq_ragne symbol within devfreq.
