Hello! This is an experimental automated report about issues detected by Coverity from a scan of next-20191031 as part of the linux-next weekly scan project: https://scan.coverity.com/projects/linux-next-weekly-scan You're getting this email because you were associated with the identified lines of code (noted below) that were touched by recent commits: 74aa7bd4c6f7 ("drm/amd/display: Make stream commits call into DC only once") Coverity reported the following: *** CID 1487396: Null pointer dereferences (FORWARD_NULL) /drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c: 5901 in amdgpu_dm_commit_planes() 5895 5896 if (dc_plane && !dc_plane->tiling_info.gfx9.swizzle) 5897 swizzle = false; 5898 5899 bundle->surface_updates[planes_count].surface = dc_plane; 5900 if (new_pcrtc_state->color_mgmt_changed) { vvv CID 1487396: Null pointer dereferences (FORWARD_NULL) vvv Dereferencing null pointer "dc_plane". 5901 bundle->surface_updates[planes_count].gamma = dc_plane->gamma_correction; 5902 bundle->surface_updates[planes_count].in_transfer_func = dc_plane->in_transfer_func; 5903 } 5904 5905 fill_dc_scaling_info(new_plane_state, 5906 &bundle->scaling_infos[planes_count]); If this is a false positive, please let us know so we can mark it as such, or teach the Coverity rules to be smarter. If not, please make sure fixes get into linux-next. :) For patches fixing this, please include these lines (but double-check the "Fixes" first): Reported-by: coverity-bot <keescook+coverity-bot@xxxxxxxxxxxx> Addresses-Coverity-ID: 1487396 ("Null pointer dereferences") Fixes: 74aa7bd4c6f7 ("drm/amd/display: Make stream commits call into DC only once") Thanks for your attention! -- Coverity-bot
