conflicting declaration of prom_getcmdline()

[Ulrich Eckhardt <eckhardt@satorlaser.com>]

Greetings!

I just stumbled over arch/mips/au1000/common/prom.c, which contains a function 
defined like this:
  char* prom_getcmdline(void);
  EXPORT_SYMBOL(prom_getcmdline);
while there are implementations that define the function as
  char* __init prom_getcmdline();
Further, there are several declarations throughout sourcefiles and in 
include/asm-mips/mips-boards/prom.h and include/asm-mips/sgialib.h. Just grep 
for it and you'll see the mess.

If anyone tells me which one is right and cares to explain why I hereby 
volunteer to create a patch. ;)

Apart from that, some code in arch/mips/au1000/common/prom.c is unnecessarily 
complicated.

cheers

Uli
