> Fix misplaced newlines in conditional log messages.
Please don't do this, the way the author formatted the strings
was intentional, they intended to print out:
NAME: cs89%c0%s rev %c found at %#8lx IRQ %d ADDR %pM
But now you are splitting it into multiple lines. Also, you're
printing the IRQ information after register_netdev() which is
bad. As soon as register_netdev() is called, the driver's
->open() routine can be invoked, and during which time some
log messages could be emitted during that operation.
And that would cut the probe messages up.
I know how you got to this state, you saw a reference to dev->name
before it had a real value. You just removed the "eth%d" string
entirely. And since you removed the dev->name reference, you had
no reason to move log messages after register_netdev() at all.
Anyways, you can also see the intention of the author here becuase
they have _explicit_ leading newlines in the error path messages that
come after the inital probe printk.
The real way to fix the early dev->name reference is to replace it
with a dev_info() call and have it use the struct device name rather
than the netdev device one.
Again, I think you really shouldn't be making these small weird
changes to these old drivers.
