Rather than (incompletely [0]) re-implementing drm_gem_mmap() and drm_gem_mmap_obj() helpers, call them directly from the rockchip mmap routines. Once the core functions return successfully, the rockchip mmap routines can still use dma_mmap_attrs() to simply mmap the entire buffer. [0] Previously, we were performing the mmap() without first taking a reference on the underlying gem buffer. This could leak ptes if the gem object is destroyed while userspace is still holding the mapping.
