This patch (as1644) fixes a race that occurs during startup in uhci-hcd. If the IRQ line is shared with other devices, it's possible for the handler routine to be called before the data structures are fully initialized. The problem is fixed by adding a check to the IRQ handler routine. If the initialization hasn't finished yet, the routine will return immediately.

So, by default initialize ep->maxburst to 1 for ep0.

The tty is NULL when the port is hanging up. chase_port() needs to check for this. This patch is intended for stable series. The behavior was observed and tested in Linux 3.2 and 3.7.1. Johan Hovold submitted a more elaborate patch for the mainline kernel.

Some touchscreens have buggy firmware which claims remote wakeup to be enabled after a reset. They nevertheless crash if the feature is cleared by the host. Add a check for reset resume before checking for an enabled remote wakeup feature. On compliant devices the feature must be cleared after a reset anyway.
