From 61e8b858abe38c1042135065c59f7d339194b50b Mon Sep 17 00:00:00 2001 From: Alan Stern Date: Mon, 9 Apr 2007 11:52:31 -0400 Subject: EHCI: fix remote wakeup regression in 2.6.21-rc There is one significant difference between the behavior of root hubs (as embodied in host controller hardware) and external hubs: When a remote-wakeup signal is received, an external hub sends an interrupt message at the _end_ of the resume sequence but a root hub generates and interrupt at the _beginning_ of the resume sequence. The host system must poll for the end of the sequence. When ehci-hcd was converted to interrupt-driven operation instead of using polling, the remaining need for this particular poll was overlooked. This patch (as894) fixes the problem.
