Subject: [PATCH 0/2] ALSA: hda: Fix Cirrus ACPI device reference leaks
Date: Tue, 28 Apr 2026 15:44:15 +0800 [thread overview]
Message-ID: <20260428074415.GA1632446@chcpu16> (raw)
This series fixes two missing acpi_dev_put() cases in Cirrus HDA side-codec
ACPI lookup paths.
Patch 1 drops the lookup reference after synthesizing the companion in
cs35l56_hda_read_acpi().
Patch 2 drops the lookup reference on the early !physdev error path in
cs35l41_hda_read_acpi().
