Since the addition of WARN_ON() in nand_subop_get_data/addr_len() helpers, this driver will produce harmless warnings (mostly at probe) just because it always called the *_data_len() helper in the parsing function (even on non-data instructions, where this value is meaningless and unneeded.
Fix these warnings by deriving the length only when it is relevant.

You can drop the above line this 760c435e0f85 was merged in 4.19-rc1.
If you're okay with these changes, no need to send a new version, I'll fix it when applying.
Thanks,
Boris
