Subject[PATCH] rfkill-input doesn't work until 5 minutes after boot
rfkill-input implements debounce as follows:

if (time_after(jiffies, task->last + msecs_to_jiffies(200))) {
However, task->last is initialised to 0 while jiffies starts at -300*HZ.
Any input within 5 minutes of kernel start is therefore ignored. Fix by
initialising task->last correctly.
