net/af_iucv: right-size the uid variable in iucv_sock_bind()
smatch complains about net/iucv/af_iucv.c:624 iucv_sock_bind() error: memcpy() 'sa->siucv_user_id' too small (8 vs 9) Which is absolutely correct - the memcpy() takes 9 bytes (sizeof(uid)) from an 8-byte field (sa->siucv_user_id). Luckily the sockaddr_iucv struct contains more data after the .siucv_user_id field, and we checked the size of the passed data earlier on. So the memcpy() won't accidentally read from an invalid location. Fix the warning by reducing the size of the uid variable to what's actually needed, and thus reducing the amount of copied data.

Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
