And if positive, it might be fewer pages than were requested. And if fewer pages than requested, then the caller should return (via put_page()) the pages that *were* pinned. This driver was doing that *except* that it had a problem with the -errno case, which was being stored in an unsigned int, and which would case an interesting mess if it ever happened: nr_pages would be interpreted as a spectacularly huge unsigned value, rather than a small negative value. Also, it was unnecessarily overriding a potentially informative -errno, with -EINVAL, in some cases. Instead: clamp the nr_pages to zero or positive, so that the error handling works. And return the -errno value from get_user_pages*(), unchanged, if we get one. And explain this with comments, seeing as how it is error-prone.
