Subject: of atmel_pmecc_destroy_user

Hi Boris and co,
  One of my scripts noticed that 'atmel_pmecc_destroy_user'
isn't called anywhere; I was going to delete it, but hmm, I wonder
if it's actually a missing call and leaking (in the unlikely case
the device was ever removed).

It was added by your:
  commit f88fc122cc34c2545dec9562eaab121494e401ef

    mtd: nand: Cleanup/rework the atmel_nand driver

and I see the allocation in:
     user = kzalloc(size, GFP_KERNEL);
       in
     nand->pmecc = atmel_pmecc_create_user(nc->pmecc, &req);
       called in atmel_nand_pmecc_init
         from atmel_nand_ecc_init
           from atmel_hsmc_nand_ecc_init
 
But I don't see any freeing.

(I don't knowingly have hardware to test a fix, although I guess
there's probably one somewhere....)

Suggestions?

Thanks,

Dave
