USB: OHCI: fix root-hub resume bug
When a suspended OHCI controller sees a port's status change, it sets both the Root-Hub-Status-Change and the Resume-Detect bits in the Interrupt Status register. Processing both these bits, the driver tries to resume the root hub twice! This patch (as807) fixes the bug by ignoring RD if RHSC is set. It also prints a slightly more informative log message when a remote-wakeup event occurs. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
