USB: improve ehci_watchdog's side effect in CPU power management
ehci_watchdog will wake up CPU very frequently so that CPU stays at C3 very short, average residence time is about 50 ms on Aspire One, but we expect it should be about 1 second or more, so this kind of periodic timer is very bad for power saving. We can't remove this timer because of some bad USB controller chipset, but at least we should reduce its side effect to as possible as low. This patch can make CPU stay at C3 longer, average residence time is about twice as long as original. Please consider to apply it, thanks Signed-off-by: Yi Yang <yi.y.yang@intel.com> Cc: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
