I would be even more aggressive at reducing lines of code.

For example do direct returns when ok to do:
        if (pos != 0 || count != sizeof(struct qib_flash))
                return -EINVAL;

        tmp = memdup_user(buf, count);
        if (IS_ERR(tmp))
                return PTR_ERR(tmp);

The bail_tmp: label is then not needed.
