From: Jon Schindler <jkschind@xxxxxxxxx>
I apologize, there was an error in the last two versions I sent. I'm not sure what's happening, but
I've recut and pasted the text. If that doesn't work this time, I may need to use a different mail client.
As this is the first patch I have submitted, please let me know if there are any errors that I have made
or tips that I can follow for next time.

As part of the kernel janitor projected listed at http://kernelnewbies.org/KernelJanitors/Todo/ApiChanges
I have made the following changes:
-prototypes for init_module were replaced with static function definitions
that are exported using module_init()
-prototypes exported using cleanup_module(void) were replaced with a
static internal function that is exported through module_exit().

The following files are affected:
drivers/block/floppy.c
drivers/block/ps2esdi.c
drivers/char/drm/drm_drv.c
drivers/char/ip2/ip2main.c
drivers/ide/ide.c
drivers/net/3c501.c
drivers/net/3c505.c
drivers/net/3c507.c
drivers/net/3c515.c
drivers/net/3c523.c
drivers/net/3c527.c
drivers/net/82596.c
