In the original code, it's clear that the programmer thought about what happens when the device_wakeup_detach() returns NULL but in the new code that's not clear. I guess the information is still there in the git archive, but why hide the good code by covering it with confusing code? regards, dan carpenter -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
