Is it necessary to nest the function to fix this problem? Are you sure no other function will ever need str_tx_byte?
As far as I can see, the global variable is only used for communication between the two functions, of which one is a callback. By nesting the function, the variable can be local.
The only alternative I see is to rewrite that part entirely.
Dumb question: Can we simply copy the v3 code to v2 here? That would also give us nice benefits like printk buffering in the long term.
