[PATCH] mips: prom_free_prom_memory() returns `unsigned long'

[a.othieno@bluewin.ch (Arthur Othieno)]

Hi,

Some boards have, eg.:

  arch/mips/momentum/ocelot_3/prom.c:242:void __init prom_free_prom_memory(void)

yet free_initmem() expects a return:

  arch/mips/mm/init.c:285:extern unsigned long prom_free_prom_memory(void);
  arch/mips/mm/init.c:291:	freed = prom_free_prom_memory();

Fix those up and return 0 instead, just like everyone else does.
