Unless I'm mistaken, it seems like qcom_smd_parse_edge() will also print a more useful error in every other case, except after the mbox_chan != -ENODEV check.. How about making that: if (PTR_ERR(edge->mbox_chan) != -ENODEV) { ret = dev_err_probe(dev, PTR_ERR(edge->mbox_chan), "failed to acquire IPC mailbox\n"); goto put_node; } And then drop the error print here in qcom_smd_register_edge(). It would bring us the devices_deferred tracking, and it would avoid the double print in all other cases. Regards, Bjorn > goto unregister_dev; > } > > > -- > 2.44.0 >

When the mailbox driver has not probed yet, skip printing the error message since it's just going to confuse users. Signed-off-by: Luca Weiss <luca@z3ntu.xyz> --- drivers/rpmsg/qcom_smd.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-)
