Subject: migration/rdma: Clean up qemu_rdma_poll()'s return type
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=b72eacf3c014ba7cbccee57a791589822e175580;p=qemu.git

migration/rdma: Clean up qemu_rdma_poll()'s return type

qemu_rdma_poll()'s return type is uint64_t, even though it returns 0,
-1, or @ret, which is int.  Its callers assign the return value to int
variables, then check whether it's negative.  Unclean.

Return int instead.
