Subject: [PATCH 6/6] lib: Use existing define with polynomial
Date: Tue, 17 Jul 2018 18:05:41 +0200 [thread overview]
Message-ID: <20180717160541.3843-7-krzk@kernel.org> (raw)
In-Reply-To: <20180717160541.3843-1-krzk@kernel.org>
Do not define again the polynomial but use header with existing define.
Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org>
