This TODO and "if (true)" looks odd.

Ditto.
Also, I find the wording "tweak" a bit vague, "tweak" really means
nothing specific. What about prepare/unprepare instead of tweak/restore ?
Also, shouldn't nand_ecc_init_req_tweaking() also allocate the struct
nand_ecc_req_tweak_ctx so that this structure remains internal ?
