commit 975323ab8f116667676c30ca3502a6757bd89e8d upstream.

The parallel-port restore operations is called when a driver claims the
port and is supposed to restore the provided state (e.g. saved when
releasing the port).

Fixes: b69578df7e98 ("USB: usbserial: mos7720: add support for parallel port on 
moschip 7715")
