fwiw I'm fine with adding new fbdev drivers to staging, that really
doesn't hurt anyone. Adding drm drivers to staging tends to be pain,
least because if we need to do any changes to helpers there's a
cross-tree cordination problem usually, and the benefit of staging
hasn't in the past really outweighted that. Plus I try for us to land
new drivers when they're good enough directly into drivers/gpu, and
not aim for perfect.
