SubjectRe: [PATCH 1/1] cpufreq: cpufreq-cpu0: use the max voltage instead of voltage-tolerance

Well, unfortunately your patch is plainly wrong, because there are
in-tree users of voltage-tolerance right now. How can you simply remove
it from driver with ignoring these users?

$ git grep voltage-tolerance arch/arm/boot/dts
arch/arm/boot/dts/am33xx.dtsi: voltage-tolerance = <2>; /* 2 percentage */
arch/arm/boot/dts/imx27.dtsi: voltage-tolerance = <5>;
arch/arm/boot/dts/r8a73a4-ape6evm-reference.dts: voltage-tolerance = <1>; /* 1% */
arch/arm/boot/dts/r8a73a4-ape6evm.dts: voltage-tolerance = <1>; /* 1% */
arch/arm/boot/dts/sh73a0-kzm9g-reference.dts: voltage-tolerance = <1>; /* 1% */
