This patch has been added to the 3.12 stable tree. If you have any
objections, please let us know.
===============
commit d1e61fe49fd450be15d402ac353784f5ba8a624e upstream.
Unloading the fs3270 kernel module does not remove the created
"3270/tub" device. Reloading the module then causes a sysfs warning:
"sysfs: cannot create duplicate filename '/devices/virtual/3270/3270!tub'".
Call device_destroy() in the module exit function to solve this issue.
