From bf87ce5a06ed2cb13ad04f065706cf36ab021549 Mon Sep 17 00:00:00 2001 From: Alan Stern Date: Thu, 5 Apr 2007 16:07:44 -0400 Subject: [PATCH] USB: remove unneeded WARN_ON This patch (as883) removes an out-of-date WARN_ON from the main HCD endpoint-disable routine. The warning is triggered whenever an endpoint is disabled while the root hub is suspended. In the past that may not have been legal, but it definitely is legal now. Merely unbinding a USB driver will do it. Furthermore, I've never seen any occurrences of this warning that really did signal an actual bug or error condition. At this point it has outlived its purpose.
