[PATCH] driver core: Add the ability to unbind drivers to devices from userspace

From: Jon Smirl
Date: Sun Jul 24 2005 - 23:10:37 EST

I just pulled from GIT to test bind/unbind. I couldn't get it to work;
it isn't taking into account the CR on the end of the input value of
the sysfs attribute. This patch will fix it but I'm sure there is a
cleaner solution.
