I tried splitting the earlier [PATCH 3/6], therefore a new patch for merging
various Hamming ECC schemes was spawned. But, I could not clean more
because I would have broken the NAND functionality in between the
patches.
My apologies, I missed some of you other comments, so I'm preparing
next version by splitting [PATCH 3/6] into more sub-patches for ease of
review.
Most #ifdef were put to suppress warning of un-used functions during
compile time. So those cannot be removed, otherwise this patch would
give compile warnings under randconfig.

Agreed, I update commit log to be more explicit that here nand_bch.c
actually encapsulates lib/bch.c.
Here also I cannot remove #ifdef across nand_bch_free() because
it frees some bch control data, which would not be defined for all
ecc-schemes (it is specific to xx_SW ecc schemes). Hence removing
#ifdef here would give null-pointer exception.

Yes I understood this, but I think it would be still good to explicitly
free the resources in case of "module_remove()", because that would
free all resources instantaneously without waiting for devm_ to
iterate thru the list when it wakes-up (I guess).
I'm not knowledgeable of exact implementation of devm_ and how
often does it iterates the list and frees the resources for corresponding
un-registered devices. So trusting you I'll include your feedbacks here.
with regards, pekon
