The wrapper is not needed. > Nack, we did an effort to remove all public users of cros_ec_cmd_xfer() in favour of cros_ec_cmd_xfer_status() and you are reintroducing again. You can do the same but using cros_ec_cmd_xfer_status(). In fact, your patch will not build on top of the upcoming changes. > Signed-off-by: Yu-Hsuan Hsu > --- > sound/soc/codecs/cros_ec_codec.c | 9 ++++++++- > 1 file changed, 8 insertions(+), 1 deletion(-) > > diff --git a/sound/soc/codecs/cros_ec_codec.c b/sound/soc/codecs/cros_ec_codec.c > index 8d45c628e988e..a4ab62f59efa6 100644 > --- a/sound/soc/codecs/cros_ec_codec.c > +++ b/sound/soc/codecs/cros_ec_codec.c > @@ -90,10 +90,17 @@ static int send_ec_host_command(struct cros_ec_device *ec_dev, uint32_t cmd, > if (outsize) > memcpy(msg->data, out, outsize); > > - ret = cros_ec_cmd_xfer_status(ec_dev, msg); > + ret = cros_ec_cmd_xfer(ec_dev, msg); > if (ret < 0) > goto error; > > + if (msg->result != EC_RES_SUCCESS) { > + dev_err(ec_dev->dev, "Command %d failed: %d\n", cmd, > + msg->result); > + ret = -EPROTO; > + goto error; > + } > + > if (insize) > memcpy(in, msg->data, insize); > >
