Subject: [PATCH 4/9] ARM: boards: protonic-imx6: Always free allocated alias string
Date: Thu, 16 Jun 2022 15:11:09 +0200	[thread overview]
Message-ID: <20220616131114.214628-5-robin@protonic.nl> (raw)
In-Reply-To: <20220616131114.214628-1-robin@protonic.nl>

The memory required to store the string needs to be freed on success
as well since it's no longer used.
