commit: d16ba48774913d244c7eb894d28d8ae2c019a827 From: Alan Stern <[email protected]> Date: Wed, 19 Sep 2012 17:02:29 -0400 Subject: USB: EHCI: convert warning messages to debug-level
This patch (as1606) converts two warning messages in the ehci-hcd driver to debug messages, and adds a little extra information to each. The log messages occur when an EHCI controller takes too long (more than 20 ms) to turn its async or periodic schedule on or off. If this happens at all, it's liable to happen quite often and there's no point spamming the system log with these warnings. Furthermore, there's nothing much we can do about it when the problem happens.
