[PATCH 15/23] mtd: nand: raw: diskonchip: Marking unused variables as __always_unused

[Lee Jones]

'dummy' is never checked (as per the nomenclature) and the use of
'emtpymatch' is currently #if 0'ed out.  We could also #if 0 the
declaration, but #ifery is pretty ugly, so I like to keep it to a
minimum.

It took me some time to spot why the "mtds" change is there, so maybe
add to the commit msg:
"Correct also typo controoler -> controller."

It looks like this is a fix of patch 03/23 :) Maybe this entire patch
can be squashed with patch 03/23 btw?

Perhaps we should not add blank lines if the rest of the file does not
already have such spacing (see below).

May I ask; what is the plan for these patches please?

Do you plan on taking the ones that do not require re-work, rather
than fixing up and re-submitting the whole set.  It would certainly
save a lot of mailing list churn if that were the case.

Either way, let me know and I will abide by your decision.

I would prefer receiving a v2 with all the patches if you don't mind.
