From 2239aa3d15056e4be807eaa8d778b247156ce552 Mon Sep 17 00:00:00 2001 From: Stephen Warren Date: Wed, 20 Nov 2013 14:06:22 -0700 Subject: [PATCH] cpufreq: tegra: don't error target() when suspended d4019f0a92ab "cpufreq: move freq change notifications to cpufreq core" added code to the cpufreq core to print an error if a cpufreq driver's .target() function returned an error. This exposed the fact that Tegra's cpufreq driver returns an error when it is ignoring requests due to the system being suspended. Modify Tegra's .target() function not to return an error in this case; this prevents the error prints. The argument is that since the suspend hook can't and doesn't inform the cpufreq core when its requests will be ignored, there's no way for the cpufreq core to squelch them, so it's not an error for the requests to keep coming. This change make the Tegra driver consistent with how the Exynos handles the same situation. Note that s5pv210-cpufreq.c probably suffers from this same issue though.
