Subject: [PATCH v2 0/3] ASoC: cs35l56: Fix some cleanup memory leaks
Date: Wed, 10 Jun 2026 10:34:29 +0100	[thread overview]
Message-ID: <20260610093432.557375-1-rf@opensource.cirrus.com> (raw)

These are for-next.

They are not urgent because it only leaks memory if the driver failed to
component_probe or is removed, which wouldn't happen in normal use.

This series fixes some memory leaks:
- The memory allocated by wm_adsp/cs_dsp was not freed.
- If component_probe() failed it didn't clean up.

The addition of this cleanup in patch #3 exposes an existing possible
double-free of the debugfs, which is fixed in patch #2.

Changes in V2:
- Added patch to prevent the double-free of debugfs
