Subject: chardev-socket: remove useless if
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=ff82fab792cba01f29a700e4c4ac660753961fbb;p=qemu.git

chardev-socket: remove useless if

This trips Coverity, which believes the subsequent qio_channel_create_watch
can dereference a NULL pointer.  In reality, tcp_chr_connect's callers
all have s->ioc properly initialized, since they are all rooted at
tcp_chr_new_client.
