Build error for NVIDIA Tegra DRM since 4.14-rc1

Build error for NVIDIA Tegra DRM since 4.14-rc1

[Linus Lüssing]

Hi,

Sorry, did not search for the exact commit yet, but since v4.14-rc1
I get a build error when trying to build the ARM multi_v7_defconfig
target:

~~~~~~~~~~

~~~~~~~~~~

v4.14-rc2 fails, too. v4.13.2 and v4.13.3 worked fine with multi_v7_defconfig.

Setting CONFIG_DRM_TEGRA=n for v4.14-rc1 or v4.14-rc2 helps for
the build to succeed, too.

Yes, sorry about this, we are aware [0] and there is a fix on its way
upstream [1].

Cheers
