Amit Shah 299fb61c08 virtio: console: Disable lseek(2) for port file operations
The ports are char devices; do not have seeking capabilities.  Calling
nonseekable_open() from the fops_open() call and setting the llseek fops
pointer to no_llseek ensures an lseek() call from userspace returns
-ESPIPE.
