Subject: [PATCH] char/adi: Remove redundant less-than-zero check in adi_write()
Date: Wed, 3 Sep 2025 22:23:51 +0200 [thread overview]
Message-ID: <20250903202350.182446-2-thorsten.blum@linux.dev> (raw)
The function parameter 'size_t count' is unsigned and cannot be less
than zero. Remove the redundant condition.
