Right. Suraj likely has just missed that part, because having "IRQ safety IRQ" statement sounds clumsy and not looking alike the others optional IRQ info-messages, meanwhile having "IRQ sfty" instead would be more correct. Anyway, Suraj, could you please at least fix the info-string and resubmit the series? With that fixed feel free to add my tag: Reviewed-by: Serge Semin <fancer.lancer@gmail.com> Note I am not insisting in using dev_dbg() instead of dev_info() since from one side the sfty IRQ line getting procedure would look alike to the others optional IRQs retrieved in this method, from another side using dbg log-level here and info-level for others IRQ wouldn't look coherent. So it seems reasonable to use info-level everywhere and convert to dbg-level at once (eventually). -Serge(y) > > > + } > > + > > stmmac_res->addr = devm_platform_ioremap_resource(pdev, 0); > > > > return PTR_ERR_OR_ZERO(stmmac_res->addr); > > -- > > 2.25.1 > > > >
