Commit 473b79057bbd shouldn't be merged until all of the IDIO-16 legacy
interface is first removed.
Bart, would you revert all of the "Migrate IDIO-16 GPIO drivers to
regmap API" patches [0]? That patchset needs to be revised anyway to
prevent conflicts with the handle_mask_sync() API change [1]; I'll
submit a v3 later this week that resolves the incompatibilies and
rebase on the latest gpio/for-next.
