Arnd, could you merge the patch? I think that Benjamin could also merge it.

The DRM_STM driver can be built independently of the framebuffer layer, but it causes a Kconfig warning:

WARNING: unmet direct dependencies detected for FB_PROVIDE_GET_FB_UNMAPPED_AREA Depends on [n]: HAS_IOMEM [=y] && FB [=n] Selected by [y]: - DRM_STM [=y] && HAS_IOMEM [=y] && DRM [=y] && (ARCH_STM32 [=n] || ARCH_MULTIPLATFORM [=y])

Selecting FB_PROVIDE_GET_FB_UNMAPPED_AREA actually has no effect if CONFIG_FB is disabled, so we can make it a conditional 'select' instead.
