Subject: drm/mediatek: include dma-mapping header
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=7837951a12fdaf88d2c51ff0757980c00072790c;p=uclinux-h8%2Flinux.git

drm/mediatek: include dma-mapping header

Although it builds fine here in my arm cross compile, it seems
either via some other patches in -next or some Kconfig combination,
this fails to build for everyone.

Include linux/dma-mapping.h should fix it.
