bcm47xxnflash_remove() is supposed to unregister the NAND device previously
registered in bcm47xxnflash_probe(), but the current implementation just
test for the always NULL ->mtd platform data field (and does not call the
right function to unregister it).
Kill the useless ->mtd field in struct bcma_nflash, and release the real
NAND device in bcm47xxnflash_remove().

Hmm, looks awfully similar...

My bad, I completely overlooked it, even though I was in Cc of this
patch.
I acked it, could you apply it before my series so that I can can
adjust the bcma patch?
Best Regards,
Boris
