[PATCH v6 16/22] usb: dwc2: host: Add scheduler logging for missed SOFs

2016-01-28 Thread Douglas Anderson
We'll use the new "scheduler verbose debugging" macro to log missed SOFs. This is fast enough (assuming you configure it to use the ftrace buffer) that we can do it without worrying about the speed hit. The overhead hit if the scheduler tracing is set to "no_printk" should be near zero.
