If anyone has any objections, please let me know. ------------------ From: Pengjie Zhang [ Upstream commit 03120e1425262c7d11f93362a88e579a1720390b ] The conservative governor documentation incorrectly states that setting freq_step to 0 will use the default 5% frequency step. In reality, since at least commit 8e677ce83bf4 ("[CPUFREQ] conservative: fixup governor to function more like ondemand logic"), freq_step=0 has always caused the governor to skip frequency updates entirely. Correct the documentation to reflect the actual behavior: freq_step=0 disables frequency changes by the governor entirely.
