Re: [PATCH] 2.4.4-ac11 network drivers cleaning

Patch looks decent. Adding module descriptions was quite nice. One
flaw that is repeated multiple times is that you add

        #ifdef MODULE
        printk(version);
        #endif

in an ISA driver's probe routine. This instead should always be the
first operation of init_module.

Also make sure to go through the 'ac' patch and review the earlier
version string changes. Some of them were buggy, like

        static const char version[] __initdata =
        "...";

const combined with __[dev]initdata causes a section type conflict. A
few of those popped up after the earlier patch was applied to 'ac'.

Finally, I don't know if I mentioned this earlier, but to be complete
and optimal, version strings should be a single variable 'version', such
that it can be passed directly to printk like

        printk(version);

Some net drivers are already like this, as I'm sure you know. Some net
drivers have 'version', 'version2', 'version3' instead of just one long
string. Some net drivers add KERN_xxx at printk time, instead of adding
it to the 'version' var. Some net drivers do the following, which is
really silly considering you know all strings at compile time:

        printk(KERN_INFO "%s\n", version);
