The subsystem should not BUG() when calculate, correct, or hwctl are missing, if the methods that call them have been overridden.

This should go through the 83xx custodian, but I haven't seen this yet?
Why should it go through 83xx? It's a patch against generic NAND code.
Anyway, it does not apply any more:
Applying Don't panic if a controller driver does ecc its own way. error: patch failed: drivers/mtd/nand/nand_base.c:2593 error: drivers/mtd/nand/nand_base.c: patch does not apply fatal: sha1 information is lacking or useless (drivers/mtd/nand/nand_base.c). Repository lacks necessary blobs to fall back on 3-way merge. Cannot fall back to three-way merge.
Did you try applying it against the 2.6.22.1 branch of the nand repository (IIRC, the non-commit-message patch comment specified that)?
