Subject: nbd-client: Use correct macro parenthesization
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=af5eeb2c3b691e13b55724e4b6d831cb054ffebe;p=qemu.git

nbd-client: Use correct macro parenthesization

If 'bs' is a complex expression, we were only casting the front half
rather than the full expression.  Luckily, none of the callers were
passing bad arguments, but it's better to be robust up front.
