Fix misplaced newlines in conditional log messages.
Add missing printk severity levels.
Log the MAC address after the interface gets a meaningful name.
Drop deprecated "out of memory" message as per checkpatch advice.

Before expansion, dev->name is "eth%d", so log the slot number instead.
Log the MAC address after the interface gets a meaningful name.
Disambiguate the two identical "Card type %s is unsupported" messages.
Fix the duplicated driver name in the pr_warn() message.
Fixes: 3a3a7f3b7fbd ("net: mac8390: Allow modular build")

Add missing printk severity levels.
Don't print the valid silicon revision number (it's in the source).
Avoid KERN_CONT usage as per advice from checkpatch.
Avoid ifdef around printk calls.

Log the MAC address after the interface gets a meaningful name.
Drop redundant debug messages for FIFO events recorded in the
interface statistics (consistent with mace.c).

To: David S. Miller; +Cc: netdev, linux-kernel, Russell King, linux-arm-kernel
The patch which introduced the 8390 core module parameter 'msg_enable'
failed to do anything useful with it: it merely causes an ancient
version string to be logged.
Remove the other code that logs the same string. Use the msg_enable
module parameter as the default value for ei_local->msg_enable.
Otherwise, some 8390 modules have no way to set ei_local->msg_enable.
Also fix two more issues arising from the same patch: indentation
mistakes and pointless static variables.
Fixes: c45f812f0280 ("8390 : Replace ei_debug with msg_enable/NETIF_MSG_* feature")

The only version of smc9194.c with Mac support is the one in the
linux-mac68k CVS repo. AFAIK that driver never made it to the mainline.
Despite that, as of v2.3.45, arch/m68k/config.in listed CONFIG_SMC9194
under CONFIG_MAC. This mistake got carried over into Kconfig in v2.5.55.
(See pre-git era "[PATCH] add m68k dependencies to net driver config".)

Finn, I'm finding real bugs in this series and seriously if you cannot
test these changes in some way please leave this code alone.
For example, you're removing the "once_is_enough" logic from
mac89x0_probe().
But you can't do that. The probe function can in fact be called
multiple times, from drivers/net/Space.c It gets called in a loop
iterating over different 'unit' argument values.
Unless you're making stylistic changes where you can prove the object
code resulting is still the same, you really should not be playing
with fire by trying to remove "dead code" like this in legacy drivers
you cannot fully test.
Thank you.

Well, this series has been tested on SONIC, MACE and 8390 devices. I do
have 89x0 hardware but it is stored elsewhere and I can't get to it right
now.

I take your point. I overlooked the Space.c logic. But that's not the
whole story here.

Testing shows that mac8390 doesn't probe any devices unless it is modular.
In the CONFIG_MAC8390=m case, the mac8390_probe() call in Space.c is
elided by '#ifdef CONFIG_MAC8390' and the device gets probed by
init_module() instead. (And the binaries published in the Debian archive
and the mac68k project on sourceforge all use CONFIG_MAC8390=m and
CONFIG_MAC89x0=m.)
In the CONFIG_MAC8390=y case, no device is probed (for some reason). This
test result suggests that the probe function is not actually called. Its
safe to assume that mac89x0 has the same problem as mac8390, and it
follows that the once_is_enough logic is redundant. At least, that was my
thinking when I made the change; that is, init_module() must be the only
caller of the probe function.
BTW, mac8390 does this,
if (slots & (1 << ndev->board->slot))
continue;
which is equivalent to the once_is_enough test, and I went looking for
some way to avoid this too.
Anyway, I see now that changing the once_is_enough logic is wrong. First
the bug has to be found or else bus matching implemented for nubus
drivers.

I agree, and that's why I've been careful with any code I cannot test
(like xtsonic) by making only changes that I can test (with macsonic).
I should have added tested-by tags...

Thanks for your review. I will revert the once_is_enough change, describe
the testing better and re-submit.
