Caused by commit

070955558e82 ("drm/mediatek: set DMA max segment size")

(from the drm-fixes tree) which should have included linux/dma-mapping.h

must be some Kconfig cases, it builds here fine (in -fixes at least).

Maybe something in next whacked the include file.

I'll add the include anyways and send to Linus,

Dave.
