ASoC: stm32: sai: fix OF node leak on probe
Published Jan 13, 2026

MEDIUMCVSS 3.1
EPSS 0.13%
Description
The reference taken to the sync provider OF node when probing the platform device is currently only dropped if the set_sync() callback fails during DAI probe.
Make sure to drop the reference on platform probe failures (e.g. probe deferral) and on driver unbind.
This also avoids a potential use-after-free in case the DAI is ever reprobed without first rebinding the platform driver.
