Subject: coroutine-io: Return -errno in case of error
X-Git-Tag: v2.3.0-rc1~13^2~6
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=4adf4180f284caf4ea9cd83ce37085d50a52603b;p=thirdparty%2Fqemu.git

coroutine-io: Return -errno in case of error

In case qemu_co_sendv_recvv() fails without any data read, there is no
reason not to return the perfectly fine error number retrieved from
socket_error().
