From 3e9e0c5c764704218c0960ffdb139de075afaadf Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Mon, 18 Nov 2019 11:35:25 +0100 Subject: staging/android/ion: delete dma_buf->kmap/unmap implemenation There's no callers in-tree anymore. For merging probably best to stuff this into drm-misc, since that's where the dma-buf heaps will land too. And the resulting conflict hopefully ensures that dma-buf heaps wont have a new ->kmap/unmap implemenation.
