From 50164f69f8c71377bfa3d356b8a6bc18b2197a45 Mon Sep 17 00:00:00 2001 From: Oswald Buddenhagen Date: Fri, 28 Apr 2023 11:59:38 +0200 Subject: [PATCH] ALSA: emu10k1: use the right lock in snd_emu10k1_shared_spdif_put() The function does read-modify-write cycles on the card's registers, and doesn't access mutable members of the emu data structure. I suppose this might have been a mixup due to the lock names being logically swapped.
