Andreas Persson 7305d6d407 mtd: cfi_cmdset_0002: fix crash when erasing/writing AMD cards ... commit 2394e628738933aa014093d93093030f6232946d upstream. Erasing an AMD linear flash card (AM29F016D) crashes after the first sector has been erased. Likewise, writing to it crashes after two bytes have been written. The reason is a missing check for a null pointer - the cmdset_priv field is not set for this type of card.
