This structure might have made sense many years ago, but at this point it is only used in one specific driver, and referenced in stale comments elsewhere. Rather than change the sunsu.c driver, simply move the struct to be within the exclusive domain of that driver, so it won't get inadvertently picked up and used by other serial drivers going forward. The comments referencing the now driver specific struct are updated accordingly. Note that 8250.c has a struct that is similar in usage, with the name serial8250_config; but is 100% independent and untouched here. Cc: "David S.
