[PATCH] ALSA: mtpav: restore negation dropped in guard() conversion
From: Wang Yan
Date: Tue Oct 20 2026 - 05:16:03 EST
commit 316e0074ecdc ("ALSA: mtpav: Use guard() for spin locks")
claims to be "Merely code refactoring, and no behavior change", but
it accidentally dropped the "!" from
if (! (portp->mode & MTPAV_MODE_OUTPUT_TRIGGERED))
in snd_mtpav_output_trigger().
Restore the negation.
