Sorry, I screwed up the settings in Thunderbird, hopefully I fixed the
white space/name issues now.
About the patch not applying, I used git format-patch and git apply to
test the stuff locally, was that wrong?
Here is a revised patch, I hope this is better.

Subject: [PATCH] nand_spl: Fix large page nand_command()
This patch changes the large page nand_command() routine to use a word
offset instead of a byte offset. The 'offs' argument gets divided by 2
so that the offset passed to nand_command() is still by byte offset.
Originally, the offset was not shifted and when too high an offset was
requested the nand chip would attempt to read non-existent data.
Changes for v2:
- Moved the offset calculation to outside of the OOB emulation code.
- Hopefully no more whitespace mangling.
