John Keeping ab78c74cfc drm/rockchip: fix fbdev on non-IOMMU devices ... When switching to the generic fbdev infrastructure, it was missed that framebuffers were created with the alloc_kmap parameter to rockchip_gem_create_object() set to true. The generic infrastructure calls this via the .dumb_create() driver operation and thus creates a buffer without an associated kmap. alloc_kmap only makes a difference on devices without an IOMMU, but when it is missing rockchip_gem_prime_vmap() fails and the framebuffer cannot be used. Detect the case where a buffer is being allocated for the framebuffer and ensure a kernel mapping is created in this case.
