Subject: sh: fix proc file removal for superh store queue module
From: Neil Horman <nhorman@xxxxxxxxxxxxx>
Clean up proc file removal in sq module for superh arch. currently on a
failed module load or on module unload a proc file is left registered which
can cause a random memory execution or oopses if read after unload. This
patch cleans up that deregistration.
