It's hard to do in cases like this where I use the variable
when defining another variable:

struct gemini_ethernet_port *port = netdev_priv(netdev);
void __iomem *status_reg = port->gmac_base + GMAC_STATUS;

But I understand the aesthetic, so I fix it as well as I can.

If you want me to even rewrite the above using more lines of code
to keep the aestetic (moving assignment out of the variable
definitions), tell me and I can fix that too, whatever you like.
