Subject: [patch] cpufreq: scpi-cpufreq: signedness bug in scpi_get_dvfs_info()
Message-ID: <20151022195208.GB24439@mwanda>
To: linux-arm-kernel@lists.infradead.org
List-Id: linux-arm-kernel.lists.infradead.org

The "domain" variable needs to be signed for the error handling to work.

Fixes: 8def31034d03 ('cpufreq: arm_big_little: add SCPI interface driver')
