From: Mike Hench <mhe...@elutions.com>
The eLBC NAND driver currently follows up each program/write operation with a
read-back of the page, in order to [ostensibly] fill in ECC data for the
caller. However, the page address used for this read is always -1, so the read
will never work correctly. Remove this useless (and potentially problematic)
block of code.
