Bartlomiej,
Do you need an Acked-by from Rob, or can you take it in the next round
of fixes for v4.20 ?
Just to repeat myself, previous code would call
offb_init_palette_hacks(), which in turn would do:
if (dp && !strncmp(name, "ATY,Rage128", 11)) {
with name=NULL.
Thanks

I prefer to fix this properly using node name helper in offb_init_palette_hacks(). I'll send a patch shortly. Rob

This is a partial revert of commit 5c63e407aaab ("fbdev: Convert to using %pOFn instead of device_node.name"). This is the minimal work to get a Mac Mini G4 back to a bootable state. The function offb_init_palette_hacks would need to handle the case where `name` has been set to NULL.
