Subject: [PATCH 3/7] cpufreq: qcom-hw: Make use of cpufreq driver_data for passing pdev
Date: Tue,  8 Sep 2020 13:27:12 +0530	[thread overview]
Message-ID: <20200908075716.30357-4-manivannan.sadhasivam@linaro.org> (raw)
In-Reply-To: <20200908075716.30357-1-manivannan.sadhasivam@linaro.org>

Get rid of global_pdev pointer and make use of cpufreq driver_data for
passing the reference of pdev. This aligns with what other cpufreq drivers
are doing.
