From 9fa1d7537242bd580ffa99c4725a0407096aad26 Mon Sep 17 00:00:00 2001 From: Tomi Valkeinen Date: Tue, 28 Feb 2017 10:11:45 +0200 Subject: drm/omap: fix dmabuf mmap for dma_alloc'ed buffers omap_gem_dmabuf_mmap() returns an error (with a WARN) when called for a buffer which is allocated with dma_alloc_*(). This prevents dmabuf mmap from working on SoCs without DMM, e.g. AM4 and OMAP3. I could not find any reason for omap_gem_dmabuf_mmap() rejecting such buffers, and just removing the if() fixes the limitation.
