Is this config not in tree? I don't see it in linux-next:
$ make mips-xway_defconfig
***
*** Can't find default configuration "arch/mips/configs/mips-xway_defconfig"!

Fix is obvious, even though I'm not sure what config to test it with.
Commit log below explains...
I'll git send-email it separately so the Cc get proper coverage.
Paul.

Subject: [PATCH] mtd: nand: fix implicit module.h usage in xway_nand.c
In commit d47529b2e9fe0ec2eb1f072afad8849f52e385c4 ("gpio: don't
include module.h in shared driver header") we fixed a bunch of
implicit includes and then did what the shortlog says -- remove
module.h from a gpio header.
In parallel, commit 024366750c2e04fdcda8bca685194ef0196b35fe
("mtd: nand: xway: convert to normal platform driver") added new
modular function calls to a file that now became relying on the
above module.h presence in the gpio header, since it did not
explicitly include module.h header for them as part of the change.
The problem only appears when the two dev streams are merged.
Since the file is tristate, the fix is obvious -- it needs an
explicit include of module.h header.

Nevermind ; took me a moment to realize it was using $ARCH-$DEFCONFIG
in the above kbuild test results naming. I've tested the fix on the
xway_defconfig for ARCH=mips and it works as expected.
Thanks,
Paul.
