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

[Jon Smirl <jonsmirl@gmail.com>]

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.
