Subject: [PATCH v2 1/3] staging: media: Remove duplicate NULL tests on a value in pci
Date: Thu, 3 Apr 2025 14:26:41 +0100 [thread overview]
Message-ID: <26990d4a9d4419f9d4155a40595bc213acb671a0.1743685415.git.abrahamadekunle50@gmail.com> (raw)
In-Reply-To: <cover.1743685415.git.abrahamadekunle50@gmail.com>
When a value has been tested for NULL in an expression, a
second NULL test on the same value in another expression
is unnecessary when the value has not been assigned NULL.
Remove unnecessary duplicate NULL tests on the same value that
has previously been NULL tested.
