Perhaps this'd be nicer as something like: priv->clock_mapping = ioremap(pci_resource_start(dev->pdev, priv->fw.clock_bar) + priv->fw.clock_offset, MLX4_CLOCK_SIZE); [] > + /* In case we got HCA frequency 0 - disable timestamping > + * to avoid dividing by zero > + */ > + if (!dev->caps.hca_core_clock) { > + dev->caps.flags2 &= ~MLX4_DEV_CAP_FLAG2_TS; > + mlx4_err(dev, "HCA frequency is 0.

Especially please don't use unnecessary line continuations. The compiler will concatenate these strings without the \. -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
