This patch is intended to prevent the spamming log from pm context but your firefly-reload board should have a another problem. So IIRC you still see the spamming log with polling mode, we need to dig that later but we need this two patches(at least 2/2) merged into 4.10-rc cycle to fix the boot problem. >> } >> } >> > > > >

When deploying runtime PM, it's quite verbose to print the log of ios setting. Also it's useless to print it from system PM as it should be the same with booting time. We also have sysfs to get all these information from ios attribute, so let's skip this print from PM context.
