Here it is. I'm not sure that having this code at all is really the
best approach. It means the drivers will override any autosuspend
values set by userspace when their devices are first detected.
Also there are bogus calls to device_init_wakeup(), and truly silly
preprocessor tests of the kernel version in the staging-tree file.
Nevertheless, this is the minimal fix.

USB: fix leftover references to udev->autosuspend_delay
This patch (as1436) takes care of leftover references to
udev->autosuspend_delay that didn't get removed during the earlier
conversion to the runtime-PM autosuspend API.
