Make the "Reducing compressed framebufer size" message be DRM_INFO_ONCE()
commit5.4-rM2-2.2.x-imx-squashed82152d424b
upstream. This was sort of annoying me: random:~$ dmesg | tail -1 [523884.039227] [drm] Reducing the compressed framebuffer size. This may lead to less power savings than a non-reduced-size. Try to increase stolen memory size if available in BIOS. random:~$ dmesg | grep -c "Reducing the compressed" 47 This patch makes it DRM_INFO_ONCE() just like the similar message farther down in that function is pr_info_once().
