rpmsg: qcom_smd: Correct return value for O_NONBLOCK
qcom_smd_send() should return -EAGAIN for non-blocking channels with insufficient space, so that we can propagate this event to user space. Fixes: 53e2822e56c7 ("rpmsg: Introduce Qualcomm SMD backend") Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org>
