This reverts stable commit baad618d078c857f99cc286ea249e9629159901f.
This commit is adding lines to spinand_write_to_cache_op, wheras the upstream commit 868cbe2a6dcee451bd8f87cbbb2a73cf463b57e5 that this was supposed to backport was touching spinand_read_from_cache_op. It causes a crash on writing OOB data by attempting to write to read-only kernel memory.
