Subject: [RFC 3/5] bus/uacce: remove memset before free
Date: Wed, 13 Nov 2024 10:56:02 -0800	[thread overview]
Message-ID: <20241113185720.28706-4-stephen@networkplumber.org> (raw)
In-Reply-To: <20241113185720.28706-1-stephen@networkplumber.org>

Doing memset before free maybe removed by compiler, and
is flagged by security scanning tools as potential problem.
In this case the memset is unnecessary.
