Sure, I will take another look at them. Also sorry for the delay in that printk() -> dev_*() patch you suggested, overwhelmed by some other things this week.

When someone goes and enable DEBUG for fbcon they are also able to recognize the logging, so the printing of the function name is redundant in this case. There is likely limited to no use for these few logging entries, but if they should be dropped then I expect Peilin Ye to do so as he is the only one doing active maintenance of fbcon lately.
