  "message": "USB: improve ehci_watchdog\u0027s side effect in CPU power management\n\nehci_watchdog will wake up CPU very frequently so that CPU\nstays at C3 very short, average residence time is about 50\nms on Aspire One, but we expect it should be about 1 second\nor more, so this kind of periodic timer is very bad for power\nsaving.\n\nWe can\u0027t remove this timer because of some bad USB controller\nchipset, but at least we should reduce its side effect to as\npossible as low.\n\nThis patch can make CPU stay at C3 longer, average residence time\nis about twice as long as original. \n\nPlease consider to apply it, thanks\n\nSigned-off-by: Yi Yang \u003cyi.y.yang@intel.com\u003e\nCc: David Brownell \u003cdbrownell@users.sourceforge.net\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@suse.de\u003e\n\n",
