Subject: tests: vhost-user-test: initialize 'fd' in chr_read
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=82248cd45e6f82da892127c4749ae89335217e31;p=qemu.git

tests: vhost-user-test: initialize 'fd' in chr_read

Currently when processing VHOST_USER_SET_VRING_CALL
if 'qemu_chr_fe_get_msgfds' get no fd, the 'fd' will
be a stack uninitialized value.
