Subject: [PATCH 2/2] cpufreq: show the real avail freqs with the freq_table
Date: Fri, 28 Nov 2014 10:43:39 +0800	[thread overview]
Message-ID: <1417142619-14548-3-git-send-email-wangweidong1@huawei.com> (raw)
In-Reply-To: <1417142619-14548-1-git-send-email-wangweidong1@huawei.com>

Some time, the policy's max_freq and min_freq will change, so
the avail freqs is not from the cpuinfo_min to cpuinfo_max.
Just add the check for the freq_table.
