[PATCH] USB: convert the semaphores in the sisusb driver to mutexes
From: Arjan van de Ven <arjan@infradead.org>
Convert the semaphores-used-as-mutex to mutexes in the sisusb video driver;
this required manual checking due to the "return as locked" stuff in this
driver, but the ->lock semaphore is still used as mutex in the end.
