[REGRESSION] "bind" a device to a driver doesn't not work anymore

[Éric Piel]

Hello,

After a suspend, I used to do this (to get the PS2 keyboard working 
again), and it used to work fine:
echo -n "i8042" > /sys/bus/platform/drivers/i8042/unbind ; sleep 1 ; 
echo -n "i8042" > /sys/bus/platform/drivers/i8042/bind

Unfortunately since 2.6.32-rc1, the unbind works fine, but the bind 
returns a "no such device" error now (and the binding is not done). 
After that, additional unbinds also report the error. I think 2.6.31 
worked fine. Any idea what's going wrong?

Thanks,
Eric
