    W1: ds1wm.c msleep for reset · cadd486c
    David Fries authored
    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.
