USB: make autosuspend delay a module parameter
This patch (as859) makes the default USB autosuspend delay a module parameter of usbcore. By setting the delay value at boot time, users will be able to prevent the system from autosuspending devices which for some reason can't handle it. The patch also stores the autosuspend delay as a per-device value. A later patch will allow the user to change the value, tailoring the delay for each individual device. A delay value of 0 will prevent autosuspend. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
