From 48915162b5ad598bc6fbf8959683f43664b4f6f1 Mon Sep 17 00:00:00 2001 From: Erick Karanja Date: Mon, 21 Jul 2025 14:45:53 +0300 Subject: [PATCH 1/2] ALSA: usb-audio: qcom: Adjust mutex unlock order The mutexes qdev_mutex and chip->mutex are acquired in that order throughout the driver. To preserve proper lock hierarchy and avoid potential deadlocks, they must be released in the reverse order of acquisition. This change reorders the unlock sequence to first release chip->mutex followed by qdev_mutex, ensuring consistency with the locking pattern.

During testing, multiple values were evaluated, and an incorrect value was mistakenly included in the final commit. This update fixes that error by applying the correct mask value for proper mute LED behavior.
