[PATCH 8/8] ALSA: firewire-tascam: Add missing annotation for tscm_hwdep_read_locked()

From: Jules Irenge
Date: Tue Mar 10 2020 - 21:09:50 EST


Sparse reports a warning at tscm_hwdep_read_locked()

warning: context imbalance in tscm_hwdep_read_locked() - unexpected unlock

The root cause is the missing annotation at tscm_hwdep_read_locked()
Add the missing __releases(&tscm->lock) annotation
