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.
