Currently we only check that the plane supports the pixel format of the fb we're about to feed to it. Extend it to check also the modifier, and more specifically that the combination of the format and modifier is supported.

2018-02-26drm/pl111: Remove reverse dependency on DRM_DUMB_VGA_DACThierry Reding
DRM_DUMB_VGA_DAC is a user-visible symbol. Selecting it can cause unmet direct dependencies such as this (on i386, randconfig): warning: (DRM_PL111) selects DRM_DUMB_VGA_DAC which has unmet direct dependencies (HAS_IOMEM && DRM && DRM_BRIDGE && OF) This is because DRM_DUMB_VGA_DAC depends on OF while DRM_PL111 does not. It does indirectly depend on OF via the ARM and ARM64 dependencies, but since it can also be enabled under COMPILE_TEST, randconfig can find a case where DRM_PL111 is selected without pulling in OF and not meeting the dependency for DRM_DUMB_VGA_DAC. Since select is "heavy handed", DRM_DUMB_VGA_DAC is going to be enabled regardless of the above warning and causes the following build error: ../drivers/gpu/drm/bridge/dumb-vga-dac.c: In function 'dumb_vga_probe': ../drivers/gpu/drm/bridge/dumb-vga-dac.c:207:13: error: 'struct drm_bridge' has no member named 'of_node' vga->bridge.of_node = pdev->dev.of_node; See Documentation/kbuild/kconfig-language.txt, "reverse dependencies".

2018-02-22drm/sun4i: backend: Assign the pipes automaticallyMaxime Ripard
Since we now have a way to enforce the zpos, check for the number of alpha planes, the only missing part is to assign our pipe automatically instead of hardcoding it. The algorithm is quite simple, but requires two iterations over the list of planes. In the first one (which is the same one that we've had to check for alpha, the frontend usage, and so on), we order the planes by their zpos. We can then do a second iteration over that array by ascending zpos starting with the pipe 0. When and if we encounter our alpha plane, we put it and all the other subsequent planes in the second pipe.

The Parfait (version 2.1.0) static code analysis tool found the following NULL pointer derefernce problem. - drivers/gpu/drm/drm_dp_mst_topology.c The call to drm_dp_calculate_rad() in function drm_dp_port_setup_pdt() could result in a NULL pointer being returned to port->mstb due to a failure to allocate memory for port->mstb.

2018-02-18drm/rockchip: Respect page offset for PRIME mmap callsØrjan Eide
When mapping external DMA-bufs through the PRIME mmap call, we might be given an offset which has to be respected. However for the internal DRM GEM mmap path, we have to ignore the fake mmap offset used to identify the buffer only. Currently the code always zeroes out vma->vm_pgoff, which breaks the former. This patch fixes the problem by moving the vm_pgoff assignment to a function that is used only for GEM mmap path, so that the PRIME path retains the original offset.
