My understanding it that he doesn't, as the dmabuf interface exposes not only the code written by this driver's author, but other parts of the Kernel. Even if someone consider just the dmabuf driver, I participated and actively contributed, together with other open source developers, during the 3 days discussions that happened at Linaro's forum where most of dmabuf design was decided, and participated, reviewed, gave suggestions approved the code, etc via email. So, even not writing the dmabuf stuff myself, I consider myself as one of the intelectual authors of the solution. Also, as dmabuf will also expose media interfaces, my understaning is that the drivers/media/ authors should also ack with this licensing (possible) change. I am one of the main contributors there. Alan also has copyrights there, and at other parts of the Linux Kernel, including the driver's core, from where all Linux Kernel drivers are derivative work, including this one. As Alan well said, many other core Linux Kernel authors very likely share this point of view. So, developers implicitly or explicitly copied in this thread that might be considering the usage of dmabuf on proprietary drivers should consider this email as a formal notification of my viewpoint: e. g. that I consider any attempt of using DMABUF or media core/drivers together with proprietary Kernelspace code as a possible GPL infringement.
