[PATCH] Make the "Reducing compressed framebufer size" message be DRM_INFO_ONCE()

[PATCH] Make the "Reducing compressed framebufer size" message be DRM_INFO_ONCE()

[Peter Jones]

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().

I know the feeling of seeing a message over and over again when you are already aware of that.
Specially something that tells you to change BIOS configuration...
for this reason I think it makes sense, so:

Acked-by: Rodrigo Vivi <rodrigo.vivi@intel.com>

I will just wait for CI and give a couple days to someone else to challenge.
If I end up forgetting to push it please ping me...
