Subject: [PATCH] thermal: cpu_cooling: Replace kmalloc with kmalloc_array
Date: Tue, 23 May 2017 12:33:06 +0530	[thread overview]
Message-ID: <eff10695c92ff2d2e9733987d1b06adf559c07b0.1495522926.git.viresh.kumar@linaro.org> (raw)
In-Reply-To: <1495521460.2303.4.camel@intel.com>

Checkpatch reports following:

WARNING: Prefer kmalloc_array over kmalloc with multiply
+	cpufreq_cdev->freq_table = kmalloc(sizeof(*cpufreq_cdev->freq_table) * i,

Fix that.
