From a76acbaec9b8fd74413646984d2e3626d0543e39 Mon Sep 17 00:00:00 2001 From: Haoxiang Li Date: Mon, 1 Jun 2026 01:08:04 +0200 Subject: [PATCH] accessibility: speakup: unregister tty ldisc on later init failures The ldisc registration is intentionally non-fatal, since some synth drivers do not use tty/ldisc. However, once speakup_init() continues past the registration point and later fails, the init unwind path should mirror speakup_exit() and call spk_ttyio_unregister_ldisc(). Add the missing unregister call to the error path after synth_release(), matching the normal module exit cleanup order.
