Yes, I misunderstood you there.

In that case it should work. But why do you need to cast it there?
Wouldn't it be simpler to just change the fbcons_write_support_polled
function? It isn't used anywhere else or did I miss something?

Yes it will work and it's resonable performant. We are talking about a
slow serial interface in an exception case. But anyway I'm not entirely
happy.
The compiler should make something like the following out of it:
- Look up and call the value of BSP_output_char
- Load the context (start of table + console_select + fixed offset) into
"con"
- Look up and call the value of console_instance
If you use the way I suggested below you will have about the following:
- Look up and call the value of BSP_output_char (one of the wrappers)
- Call the right function with a fixed parameter
So it's a bit shorter and beneath that you save a global variable.
