Subject: [PATCH 01/10] ASoC: fsl: fsl_qmc_audio: Check devm_kasprintf() returned value
Date: Thu, 20 Jun 2024 10:42:48 +0200 [thread overview]
Message-ID: <20240620084300.397853-2-herve.codina@bootlin.com> (raw)
In-Reply-To: <20240620084300.397853-1-herve.codina@bootlin.com>
devm_kasprintf() can return a NULL pointer on failure but this returned
value is not checked.
Fix this lack and check the returned value.
Fixes: 075c7125b11c ("ASoC: fsl: Add support for QMC audio")
