W1: ds1wm.c msleep for reset
Like the previous w1_io.c reset coments and msleep patch, I don't have the
hardware to verify the change, but I think it is safe. It also helps to
see a comment like this in the code. "We'll wait a bit longer just to be
sure." If they are going to calculate delaying 324.9us, but actually delay
500us, why not just give up the CPU and sleep? This is designed for a
battery powered ARM system, avoiding busywaiting has to be good for
battery life.
I sent a request for testers March 7, 2008 to the Linux kernel mailing
list and two developers who have patches for ds1wm.c, but I didn't get
any respons.
