This patch makes use of functions added in the previous patch. It registers ldisc during init of main speakup module and unregisters it during exit. It also removes the code to register ldisc every time a synth module is loaded. This way we only register the ldisc once when main speakup module is loaded. Since main speakup module is required by all synth modules, it is only unloaded when all synths have been unloaded. Therefore we unregister the ldisc once, when all speakup related references to the ldisc have returned. In unlikely scenario of something outside speakup using the ldisc, the ldisc refcount check in tty_unregister_ldisc will ensure that it is not unregistered while in use. The function to register ldisc doesn't cause speakup init function to fail. That is different from current behaviour where failure to register ldisc results in failure to load the specific synth module. This is because speakup module is also required by those synths which don't use tty and ldisc. We don't want to prevent those modules from loading when ldisc fails to register. The synth modules will correctly fail when trying to set N_SPEAKUP to tty, if ldisc registrationi had failed.
