There is a bug in nand prefetch read routine, which comes into effect
only if nand device is a 16-bit device (as we have in zoom boards).
This bug is effective only with below combination of conditions:
1. nand deivce, in use, is a 16 bit device
2. nand driver supports 'subpage' read
3. SW ECC is in use
This was not seen old kernel (ex: .23), because when, in early days,
we tested this (nand prefetch read in LDP boards) there was no
'subpage read' support.
Later when we had subpage read in (.27) kernel, we had hw ecc enabled
always in our internal tree. So, we missed this bug.
This patch fixes the issue.

This patch fixes a spelling error that has resulted from copy and
pasting. The location of the error was found using a semantic patch
but the semantic patch was not trying to find these errors. After
looking things over it seemed logical that this change was needed.
The patch also makes sure mtd_list is not being freed if it has not
been allocated
