[PATCH] USB dummy_hcd: Use root-hub interrupts instead of polling
This patch makes the dummy_hcd driver use emulated root-hub interrupts instead of polling. It's in the spirit of similar changes being made to the other HCDs. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
