[PATCH] drivers: nvdimm: cleanup include of badblocks.h

From: Enrico Weigelt, metux IT consult
Date: Tue Dec 15 2020 - 11:38:51 EST


* drivers/nvdimm/core.c doesn't use anything from badblocks.h on its own,
thus including it isn't needed. There's indeed indirect use, via funcs
in nd.h, but this one already includes badblocks.h.

* drivers/nvdimm/claim.c calls stuff from badblocks.h and therefore should
include it on its own (instead of relying any other header doing that)

* drivers/nvdimm/btt.h doesn't really need anything from badblocks.h and
can easily live with a forward declaration of struct badblocks (just having
pointers to it, but not dereferencing it anywhere)
