Davidlohr Bueso 530fcd16d8 ipc, shm: guard against non-existant vma in shmdt(2) ... When !CONFIG_MMU there's a chance we can derefence a NULL pointer when the VM area isn't found - check the return value of find_vma(). Also, remove the redundant -EINVAL return: retval is set to the proper return code and *only* changed to 0, when we actually unmap the segments.
