Subject: [PATCH 09/16] examples/ptpclient: fix self memcmp
Date: Thu, 14 Nov 2024 22:05:46 -0800 [thread overview]
Message-ID: <20241115060738.313190-10-stephen@networkplumber.org> (raw)
In-Reply-To: <20241115060738.313190-1-stephen@networkplumber.org>
Calling memcmp on same structure will always be true.
Replace with same conditional used elsewhere.
